Refactor the new CombinePSBT, FinalizePSBT, and FinalizeAndExtractPSBT
general-purpose functions out of the combinepsbt and finalizepsbt RPCs,
for use in the GUI code.
Remove the op== on PartiallySignedTransaction, which only checks that the
CTransactions are equal. Instead, check this directly in Merge, and return
false if the CTransactions are not equal (so the PSBTs cannot be merged.)
After refactoring general-purpose PSBT and transaction code out of RPC code,
for use in the GUI, it's no longer appropriate to throw exceptions. Instead we
now return bools for success, and take an output parameter for an error object.
We still use JSONRPCError() for the error objects, since only RPC callers
actually care about the error codes.
Move non-wallet PSBT code to src/psbt.{h,cpp}, and PSBT wallet code to
src/wallet/psbtwallet.{h,cpp}. This commit contains only code movement (and
adjustments to includes and Makefile.am.)
Factor out a new BroadcastTransaction function, performing the core work of the
sendrawtransaction rpc, so that it can be used from the GUI code. Move it from
src/rpc/ to src/node/.
Split up DecodePSBT, which both decodes base64 and then deserializes a
PartiallySignedTransaction, into two functions: DecodeBase64PSBT, which retains
the old behavior, and DecodeRawPSBT, which only performs the deserialization.
Add a test for base64 decoding failure.
Add support for the optional "pf_invalid" out parameter (which allows the caller
to detect decoding failures) to the std::string versions of DecodeBase32 and
DecodeBase64. The char* versions already have this feature.
Also, rename all uses of pfInvalid to pf_invalid to match style guidelines.

7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)
Pull request description:
Alternative (kind of) to #14938
This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.
Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.
Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".
This is built on top of #15225 in order to fix GUI issues.

A blank wallet is a wallet that has no keys, script or watch only things.
A new wallet flag indicating that it is blank will be set when the wallet
is blank. Once it is no longer blank (a seed has been generated, keys or
scripts imported, etc), the flag will be unset.

1cff3d6cb0 Change in transaction pull scheduling to prevent InvBlock-related attacks (Gleb Naumenko)
Pull request description:
This code makes executing two particular (and potentially other) attacks harder.
### InvBlock
This behavior was described well [here](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf) (page 11).
Per current implementation, if node A receives _INV_ (tx) from node B, node A sends _GETDATA_ to B and waits for _TX_ message back.
Node A is likely to receive more _INVs_ (regarding the same tx) from other peers. But node A would not send another _GETDATA_ unless it does not hear _TX_ back from node B for next 2 minutes (to save bandwidth)
Thus, if B is a malicious node, it can prevent node A from getting the transaction (even if all A’s peers have it) for 2 minutes.
This behavior seems to be an inherent limitation of the current P2P relay protocol, and I don’t see how it can be fundamentally changed (I can see workarounds which involve rewriting a lot of P2P code though).
### What does this PR fix?
The attacks I’m looking at involve preventing A from learning the transaction for 2*N minutes. To do that, an attacker has to spin up N nodes and send N _INVs_ simultaneously to node A (then InvBlocks will be queued with an interval of 2 minutes according to current implementation)
More precisely, 2 scenarios I’m looking at are:
1. An attacker censors a particular transaction. By performing InvBlock from different nodes, an attacker can execute a network-wide censorship of a particular transaction (or all transactions). The earlier an attacker founds the transaction he wants to censor, the easier it is to perform an attack. As it was pointed out by @gwillen, this is even more dangerous in the case of lightning, where transactions are known in advance.
2. Topology inference described in papers [1](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf), [2](https://arxiv.org/pdf/1812.00942.pdf) involve network-wide InvBlock. This fix would not mitigate this type of inference, but I believe it will make it more expensive to perform (an attacker would have to create more transactions and perform more rounds to learn the topology, the second paper itself notes that InvBlock isolation is important for the attack).
### How does it work
This PR introduces bias toward outbound connections (they have higher priority when a node chooses from whom it should request a transaction) and randomizes the order.
As per @gmaxwell suggestion, GETDATA requests queue is created after processing all incoming messages from all nodes.
After this fix, if the incoming messages were [I1, I2, I3, O1, O2, O3, O4], the queue for _GETDATA_ may look like [O2, O1, O3, O4, I1, I3, I2, ….].
If {I1, I2, I3} were significantly earlier (but the difference is less than TX_TIMEOUT=60 s) than others, the queue for _GETDATA_ may look like [I2, O2, O1, O3, O4, I1, I3, ….].
### Other comments:
1. This mitigation works better if the connectivity is higher (especially outbound, because it would be less likely that 2 _GETDATAs_ for inbound malicious nodes queued together)

Allows a descriptor to be imported into the wallet using `importmulti` RPC. Start and end of range can be specified for ranged descriptors. The descriptor is implicitly converted to old structures on import.
Also adds a simple test of a P2SH-P2WPKH address being imported as a descriptor. More tests to come, as well as release notes.

Avoids the need for external (BIP32) libraries to derive an address. Can be used in conjunction with `scantxoutset` as a poor mans wallet. Might be useful to test more complicated future descriptors.
~To keep it as simple as possible it only supports descriptors that result in a single address, so no `combo()` and ranges.~
As discussed recently on IRC it might make sense to put this in a separate utility along with other descriptor and psbt utility functions which don't need a chain or wallet context. However I prefer to leave that to another PR.

This introduces support for autodetecting and using the RdSeed instruction.
In addition:
* In SeedFast, only 64 bits of entropy are generated through RdRand (256 was relatively slow).
* In SeedStartup, 256 bits of entropy are generated, using RdSeed (preferably) or RdRand (otherwise).
When a wallet is created it is registered in the validation interface (in
CWallet::CreateWalletFromFile) but it is not immediately added to the
wallets list. If a shutdown is requested before AddWallet (case more
evident when -rescan is set) then m_internals can be released (in
Shutdown -> UnregisterBackgroundSignalScheduler) before the wallet and
then ReleaseWallet would call UnregisterValidationInterface with
m_internals already released.
This change forwards the shutdown request on the GUI (close the
application for instace) to the node as soon as possible. This way the
GUI doesn't have to wait for long operations to complete (rescan the
wallet for instance), instead those operations detect the shutdown
request and abort/interrupt.
Move only change that makes unsubscribeFromCoreSignals public. It must be
called if the event loop is not running otherwise core signals handlers
can deadlock.
11e0fd8d6 Descriptor expansions only need pubkey entries for PKH/WPKH (Pieter Wuille)
Pull request description:
Currently, calling `Expand` on a `Descriptor` object will populate the output FlatSigningProvider with all public keys involved in the descriptor. This is overkill, as pubkey entries are only needed when the lookup of a public key based on its hash is desired (which is the case for `pkh`, `wpkh`, and `combo` descriptors).
Fix this by pushing the population of pubkey entries down into the individual descriptor implementation's `MakeScript` function, instead of doing it generically.
This should make it easier to implement #14491 without importing P2PKH outputs for the individual public keys listed inside a multisig.

Now every RPC which can import private keys checks for whether the wallet has private keys are disabled and errors if it is. Also added an belt-and-suspenders check to `AddKeyPubkeyWithDB` to have it assert that the wallet has private keys enabled.

f1f4bb7345 Free BerkeleyEnvironment instances when not in use (Russell Yanofsky)
Pull request description:
Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map, use reference counted shared pointers and remove map entries when the last BerkeleyEnvironment reference goes out of scope.
This change was requested by @TheBlueMatt and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state.
This change does affect bitcoin behavior slightly. On startup, instead of same wallet environments staying open throughout VerifyWallets() and OpenWallets() calls, VerifyWallets() will open and close an environment once for each wallet, and OpenWallets() will create its own environment(s) later.

3c3e31c3a4 [tests] Add wallet-tool test (João Barbosa)
49d2374acf [tools] Add wallet inspection and modification tool (Jonas Schnelli)
Pull request description:
Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.
Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.
Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.

2bc4c3eaf9 Notify the GUI that the keypool has changed to set the receive button (Andrew Chow)
14bcdbe09c Check for more than private keys disabled to show receive button (Andrew Chow)
Pull request description:
Currently the Receive button in the GUI is displayed enabled or disabled by the initial state of the wallet when the wallet is first loaded. The button is only enabled or disabled depending on whether the disable private keys flag is set when the wallet is loaded. However, future changes to the wallet means that this initial state and check may no longer be accurate. #14938 introduces empty wallets which do not have private keys. An empty wallet that is loaded should have the Receive button disabled, and then it should become enabled once `sethdseed` is used so that a keypool can be generated and new keys generated. Likewise, with #14075, a wallet can be loaded with no keypool initially, so the button should be disabled. Later, public keys can be imported into the keypool, at which time the button should become enabled. When the keypool runs out again (no new keys are generated as the keypool only consists of imports), the button should become disabled.
This PR makes it so that the button becomes enabled and disabled as the keypool state changes. The check for whether to enable or disable the receive button has changed to checking whether it is possible to get new keys. It now checks for whether the wallet has an HD seed and, if not, whether the private keys are disabled. When an action happens which would make it possible for a new address to be retrieved or make it possible for a no more addresses to be retrieved, a signal is emitted which has the GUI recheck the conditions for the Receive button. These actions are setting a new HD seed, topping up the keypool, retrieving a key from the keypool, and returning a key to the keypool.

2ca632e5b4 test: Build fuzz targets into seperate executables (MarcoFalke)
fab4bed68a [test] fuzz: make test_one_input return void (MarcoFalke)
Pull request description:
Currently our fuzzer is a single binary that decides on the first few bits of the buffer what target to pick. This is ineffective as the fuzzer needs to "learn" how the fuzz targets are organized and could get easily confused. Not to mention that the (seed) corpus can not be categorized by target, since targets might "leak" into each other. Also the corpus would potentially become invalid if we ever wanted to remove a target...
Solve that by building each fuzz target into their own executable.

This change removes uses of `chainActive` and `mapBlockIndex` globals in wallet code. It is a refactoring change which does not affect external behavior.
This is the next step in the larger #10973 refactoring change, which removes all other accesses to node global variables from wallet code. Doing this is useful to provide a better defined interface between the wallet and node, and necessary to allow wallet and node code to run in separate processes in #10102.

0297be61a Allow connections from misbehavior banned peers. (Gregory Maxwell)
Pull request description:
This allows incoming connections from peers which are only banned
due to an automatic misbehavior ban if doing so won't fill inbound.
These peers are preferred for eviction when inbound fills, but may
still be kept if they fall into the protected classes. This
eviction preference lasts the entire life of the connection even
if the ban expires.
If they misbehave again they'll still get disconnected.
The main purpose of banning on misbehavior is to prevent our
connections from being wasted on unhelpful peers such as ones
running incompatible consensus rules. For inbound peers this
can be better accomplished with eviction preferences.
A secondary purpose was to reduce resource waste from repeated
abuse but virtually any attacker can get a nearly unlimited
supply of addresses, so disconnection is about the best we can
do.
This can reduce the potential from negative impact due to incorrect misbehaviour bans.

The launch-at-startup API Bitcoin Core uses on macOS where removed in macOS 10.11 leading to a segmentation-fault due to the weak-linking when not actively compiled against SDK 10.11 (`-mmacosx-version-min=10.11`)
This PR removes the launch-at-startup feature on macOS when compiled with macOS min version > 10.11 (the default is always the macOS version you compile on).
**The depends built binaries (Gitian) are not affected since we are building with min macOS 10.10.**

**Isn't there a new API from Apple?**
Yes, [there is](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLoginItems.html).

b301950df3 Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev)
faf29dd019 Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev)
Pull request description:
This PR is re-submission of #14156, which was automatically closed by github (glitch?)
Original description:
This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`.
Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused.
The rationale for this change is:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

It includes the following policy changes:
* All GetRand* functions seed the stack pointer and rdrand result
(in addition to the performance counter)
* The periodic entropy added by the idle scheduler now seeds stack pointer,
rdrand and perfmon data (once every 10 minutes) in addition to
just a sleep timing.
* The entropy added when calling GetStrongRandBytes no longer includes
the once-per-10-minutes perfmon data on windows (it is moved to the
idle scheduler instead, where latency matters less).
Other changes:
* OpenSSL is no longer seeded directly anywhere. Instead, any generated
randomness through our own RNG is fed back to OpenSSL (after an
additional hashing step to prevent leaking our RNG state).
* Seeding that was previously done directly in RandAddSeedSleep is now
moved to SeedSleep(), which is indirectly invoked through ProcRand
from RandAddSeedSleep.
* Seeding that was previously done directly in GetStrongRandBytes()
is now moved to SeedSlow(), which is indirectly invoked through
ProcRand from GetStrongRandBytes().
This guarantees that OpenSSL is initialized properly whenever randomness
is used, even when that randomness is invoked from global constructors.
Note that this patch uses Mutex directly, rather than CCriticalSection.
This is because the lock-detection code is not necessarily initialized
during global constructors.

fb3ce75807 Don't label transactions "Open" while catching up (Hennadii Stepanov)
Pull request description:
Fix#13299.
Since the default `nSequence` is `0xFFFFFFFE` and locktime is enabled, the checking `wtx.is_final` is meaningless until the syncing has completed (ref: #1026).
This PR makes the wallet mark a transaction "Unconfirmed" instead of misleading "Open for NNN more blocks" when syncing after a period of being offline.

c37851de57 rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)
Pull request description:
Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.

There was only one place in the codebase where we're directly reading >32 bytes from
the RNG. One possibility would be to make the built-in RNG support large reads, but
using FastRandomContext lets us reuse code better.
There is no change in behavior here, because the FastRandomContext constructor
uses GetRandBytes internally.
9d0e52834 implements different disk sizes for different networks on intro (marcoagner)

Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

fa48baf23e wallet: Avoid leaking locktime fingerprint when anti-fee-sniping (MarcoFalke)
453803adc9 [test] wallet_txn_clone: Correctly clone txin sequence (MarcoFalke)
Pull request description:
The wallet sets the locktime to the current height of our active chain. This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.
For reference, I visualized "locktime-reuse" with the data:
* blocks 545k-555k (both inclusive)
* locktimes<=60k
* excluding coinbase txs

ca126d490b Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)
Pull request description:
`mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.
`PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.
Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.
After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);
The resulting address `0x00000003ffdf` is then written to.

6b25f29a91 Use std::vector API for construction of test data. (Daniel Kraft)
Pull request description:
For constructing test scripts, use `std::vector` and, in particular, `std::vector::insert` to insert 20 zero bytes rather than listing the full array of bytes explicitly. This makes the code easier to read and makes it immediately obvious what the structure of the data is, without having to count the zeros to understand it.
Of course, that is a matter of taste - so if you disagree that the change makes the code easier to read, let me know.
This has been split out of #14752.

54dc13b6a2 rpc: Fix SoftForkMajorityDesc and SoftForkDesc signatures (João Barbosa)
Pull request description:
Motivated by https://github.com/bitcoin/bitcoin/pull/11913#discussion_r157798157, this pull makes `blockToJSON` and `blockheaderToJSON` free of `cs_main` locks.
Locking `cs_main` was required to access `chainActive` in order to check if the block was in the chain and to retrieve the next block index.
With the this approach, `CBlockIndex::GetAncestor()` is used in a way to check if the block belongs to the specified chain tip and, at the same time, get the next block index.

e58985c916 Log progress while verifying blocks at level 4. (Daniel Kraft)
Pull request description:
When verifying blocks at startup, the progress is printed in 10% increments to logs. When `-checklevel=4`, however, the second half of the verification (connecting the blocks again) does not log the progress anymore. (It is still computed and shown in the UI, but not printed to logs.)
This change makes the behaviour consistent, by adding the missing progress logging also for level-4 checks.

c8d9d9093b Fix broken notificator on GNOME (Hennadii Stepanov)
Pull request description:
Fix#14994; that bug was introduced in #14228 (that was my fault).
~Also this commit explicit separates~ There are two functions of the tray icon:
- a system tray widget (`QSystemTrayIcon::isSystemTrayAvailable() == true`)
- a high-level notificator via balloon messages (`QSystemTrayIcon::supportsMessages() == true`)
~These properties are mutually independent,~ e.g., on Fedora 29 + GNOME:
```
QSystemTrayIcon::isSystemTrayAvailable() == false;
QSystemTrayIcon::supportsMessages() == true;
```
UPDATE:
`supportsMessages()` makes no sense without `isSystemTrayAvailable()`: `QSystemTrayIcon::showMessage()` just not working on Fedora 29 + GNOME.

Pull request description:
Salvaged (but slightly modified) from #12138, the comment there was really helpful to wrap my head around that part of the code.
In addition, a naive reader like yours truly will first think `IsValid(BLOCK_VALID_SCRIPTS)` means the previous block was invalid. But IIUC that's not what it means. Instead, it means the block hasn't been checked for validity at the `BLOCK_VALID_SCRIPTS` level yet. So in that case the existing text "previous block index isn't valid" is wrong.

e982f0b682 Add all category options to wallet rpc help (andrewtoth)
Pull request description:
The current helptext for `listtransactions`, `listsinceblock` and `gettransaction` only list two of the five possible options for `category`. This incorrectly implies that these are the only two options, and can cause problems if the other three options aren't accounted for. Also, some of the documentation is incorrect when specifying which options are returned for which categories.
This PR updates the helptext for these RPCs and adds a functional regression test for the cases when the other three categories are returned.

`thread_local` seems to be highly controversial according to the discussion in #14953, so remove it again from the tests.
Also remove boost::thread_group in the test that uses it, since I am touching it anyway.

4d454dcb6 Refactoring with QString::toNSString (Hennadii Stepanov)
Pull request description:
This PR makes `MacNotificationHandler::showNotification()` cleaner and more readable.
The used `QString::toNSString()` function was introduced in Qt 5.2 which is minimum version now (#14725).
The behavior of `MacNotificationHandler::showNotification()` has not been changed.

This makes the above constructor explicit. The rationale is that this conversion has very significant performance effects. Making it explicit makes it easier to reason about these performance trade-offs, and helps identify possible functions that need a CMutableTransaction version.
This commit makes the minimal changes necessary to fix compilation once CTransaction(const CMutableTransaction &tx) is made explicit. In each case an explicit call `CTransaction(...)` was added. Shouldn't affect behaviour or performance.

Pull request description:
Previously the argument would be untouched if the first block scan failed. This
makes the behavior predictable, and consistent with the documentation.

Pull request description:
Overall this PR does the following:
- add top level menu Window
- add Minimize and Zoom actions to Window menu
- move Sending/Receiving address to Window
- remove Help->Debug window
- add one menu entry for each debug window tab
This removes the access to address book from the File menu.

Pull request description:
This improves a few minor issues with the RNG code:
* Avoid calling `GetRand*()` functions (which currently invoke OpenSSL, later may switch to using our own RNG pool) inside loops in addrman, networking code, `KnapsackSolver`, and `LimitOrphanSize`
* Fix a currently unreachable bug in `FastRandomContext::randbytes`.
* Make a number of simplifications to the unit tests' randomness code (some tests unnecessarily used their own RNG or the OpenSSL one, instead of using the unit test specific `insecure_rand_ctx`).
* As a precaution, make it illegal to copy a `FastRandomContext`.

dcb70b1522 Indicate -rpcauth option password hashing alg (Carl Dong)
Pull request description:
By indicating the password hashing algorithm, users of bitcoin distributions without the script in `share/rpcauth` and users who don't want to rely on said script can use alternative means to generate the password hash.
Question for reviewers: perhaps we should also indicate that it is specifically a HMAC-SHA-256 of the _**UTF-8**_ encoding of their password?

This introduces various changes to the importmulti logic:
* Instead of processing input and importing things at the same time, first
process all input data and verify it, so no changes are made in case of
an error.
* Verify that no superfluous information is provided (no keys or scripts
that don't contribute to solvability in particular).
* Add way more sanity checks, by means of descending into all involved
scripts.
8db0c3d42b Removed implicit CTransaction conversion from benchmaks (lucash-dev)
ed61abedb2 Removed implicit CTransaction constructor from tests (lucash-dev)
Pull request description:
This PR was split from #14906 and is a prerequisite for it.
It updates tests and benchmarks, removing all implicit calls to `CTransaction(CMutableTransaction&)` constructors. This will make possible making the constructor explicit in the next PR.
The original rationale for making the constructor explicit:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

24d3a7b3a [refactor] Use DescriptorImpl internally, permitting access to new methods (Pieter Wuille)
6be0fb4b3 [refactor] Add a base DescriptorImpl with most common logic (Pieter Wuille)
Pull request description:
This patch modifies the internal `Descriptor` class to optionally construct and use an "expansion cache". Such a cache is a byte array that encodes all information necessary to expand a `Descriptor` a second time without access to private keys, and without the need to perform expensive BIP32 derivations. For all currently defined descriptors, the cache simply contains a concatenation of all public keys used.
This is motivated by the goal of importing a descriptor into the wallet and using it as a replacement for the keypool, where it would be impossible to expand descriptors if they use hardened derivation.
