ef362f2773 rpc/gui: Remove 'Unknown block versions being mined' warning (Wladimir J. van der Laan)
Pull request description:
Due to miners inserting garbage into the version numbers causing false positives, the current version signalling has become completely useless. This removes the "unknown block versions" warning which has the tendency to scare users unnecessarily (and might get them to "update" to something bad).
It preserves the warning in the logs. Whether this is desirable can be a point of discussion.

3f5ad622e5 Enable PID file creation on Windows - Add available WIN PID function - Consider WIN32 in each relevant case - Add new preprocessor definitions to suppress warning - Update error message for generic OS (riordant)
Pull request description:
# Introduction
As discussed with @laanwj on IRC:
- PID file creation was never enabled for Windows, as the `pid_t` filetype is not available for it. However, the WIN32 API contains the header [`Processthreadsapi.h`](https://github.com/CodeShark/x86_64-w64-mingw32/blob/master/include/processthreadsapi.h) which in turn contains the function [`GetCurrentProcessId()`](https://docs.microsoft.com/en-gb/windows/desktop/api/processthreadsapi/nf-processthreadsapi-getcurrentprocessid). ~~This function is called at a higher level by [`_getpid()`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/getpid?view=vs-2017)~~ EDIT: `_getpid()` is not available to the MSVC compiler used in the AppVeyor build. As a result, I have changed the function call to`GetCurrentProcessId()`, which performs the same function and is available to both MinGW & MSVC.
This allows one to capture the PID in Windows, without any additional includes - the above function is already available.
- Within this PR, I have added a separate line that calls `GetCurrentProcessId()` in the case of a WIN compilation, and the usual `getpid()` otherwise. All code blocks processing PID file logic that avoid WIN32 have been changed to consider it. I have also updated the preprocessor definitions in `libbitcoin_server.vcxproj.in` to suppress a warning related to `std::strerror` for the MSVC build, that was causing the AppVeyor build to fail (see @fanquake comment below).
# Rationale
- Consistency between OS's running Bitcoin
- Applications which build off of `bitcoind`, such as novel front-end clients, often need access to the PID in order to control the daemon. Instead of designing some alternate way of doing this for one system, it should be consistent between all of them.

39e20fc54f Add missing #include. (Daniel Kraft)
Pull request description:
bd0dbe8763 introduced a dependency of `rpc/util.h` on `RPCErrorCode`, defined in `rpc/protocol.h`. The latter file is only included from `rpc/util.cpp`, though. This commit fixes the missing include, by moving the `#include` of `rpc/protocol.h` to `rpc/util.h`.

This also changes the uiInterface.LoadWallet signal argument type from
shared_ptr<CWallet> to unique_ptr<interfaces::Wallet> because CWallet is an
internal wallet class that shouldn't be used in non-wallet code (and also can't
be passed across process boundaries).
This commit does not change behavior.
fa9b60c842 Remove unused TransactionError constants (MarcoFalke)
Pull request description:
Fixup to #14978, which introduced a bunch of unused enum values, such as `UNKNOWN_ERROR`, `ERROR_COUNT` and `TRANSACTION_ERR_LAST`. None of those have a meaning in the context of an `enum class`, where the compiler can infer if all cases have been covered in a switch-case.
Also, move the global `::maxTxFee` back to the rpc caller, so it can be set on a per call basis (in the future).

**Notes for reviewers**
1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.

Pull request description:
This adds support for a descriptor-specific 8-character checksum.
Descriptors may optionally be suffixed with a `#` plus these 8 checksum characters. Any descriptor that contains a `#` at the end must be followed by a valid checksum. If the `#` is missing entirely, it is valid without checksum.
All RPCs are updated to report descriptors that include the checksum. On input, they are optional except in `deriveaddress` and `importmulti`, which require descriptors which include a checksum.
A new RPC is also added to analyse descriptors (`getdescriptorinfo`), which can be used to compute the checksum for a descriptor without.

Pull request description:
This PR adds 3 new utility RPCs for interacting with PSBTs.
`utxoupdatepsbt` updates a PSBT with UTXO information from the node. It only works with witness UTXOs because full transactions (as would be needed for non-witness UTXOs) are not available unless txindex is enabled.
`joinpsbts` joins the inputs from multiple distinct PSBTs into one PSBT. e.g. if PSBT 1 has inputs 1 and 2, and PSBT 2 has inputs 3 and 4, `joinpsbts` would create a new PSBT with inputs 1, 2, 3, and 4.
`analyzepsbt` analyzes a PSBT and determines the current state of it and all of its inputs, and the next step that needs to be done.

Adds a new option to importmulti where the pubkeys specified in the import
object can be added to the keypool. This only works if the wallet has
private keys disabled.
When private keys are disabled, still fetch keys from the keypool
if the keypool has keys. Those keys come from importing them and
adding them to the keypool.

Pull request description:
This PR allows for key origin data as defined by the descriptors document to be imported to the wallet when importing a descriptor using `importmulti`. This allows the `walletprocesspsbt` to include the BIP 32 derivation paths for keys that it is watching that are from a different HD wallet.
In order to make this easier to use, a new field `hdmasterkeyfingerprint` has been added to `getaddressinfo`. Additionally I have removed `hdmasterkeyid` as was planned. I think that this API change is fine since it was going to be removed in 0.18 anyways. `CKeyMetadata` has also been extended to store key origin info to facilitate this.

Store the master key fingerprint and derivation path in the

backwards compatibility, but all key derivation path output
uses the key origin info instead of hdKeypath.

The const_cast
```C++

Casting away `const`, especially from something as precious as the genesis block, feels really weird to me as a reader of bitcoin-core source code.

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)

~~Based on #14454#14565, last two commits only are for review.~~
Best reviewed with `?w=1`
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.

] // part of the BIP32 test vector
```
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.
