e254ff5d53 Introduce a maximum size for locators. (Gregory Maxwell)
Pull request description:
The largest sensible size for a locator is log in the number of blocks.
But, as noted by Coinr8d on BCT a maximum size message could encode a
hundred thousand locators. If height were used to limit the messages
that could open new attacks where peers on long low diff forks would
get disconnected and end up stuck.
Ideally, nodes first first learn to limit the size of locators they
send before limiting what would be processed, but common implementations
back off with an exponent of 2 and have an implicit limit of 2^32
blocks, so they already cannot produce locators over some size.
Locators are cheap to process so allowing a few more is harmless,
so this sets the maximum to 64-- which is enough for blockchains
with 2^64 blocks before the get overhead starts increasing.

With watching only inputs, we do not know how large the signatures
for those inputs will be as their signers may not have implemented
71 byte signatures. Thus we estimate their fees using the 72 byte
dummy signature to ensure that we pay enough fees.
This only effects fundrawtransaction when includeWatching is true.
When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.

faab63111d shutdown: Stop threads before resetting ptrs (MarcoFalke)
Pull request description:
On shutdown some threads would continue to run after or during a pointer reset. This leads to occasional segfaults on shutdown.
Fix this by resetting the smart pointers after all threads that might read from them have been stopped.
This should fix:
* A segfault in the txindex thread, that occurs when the txindex destructor is done, but the thread was not yet stopped (as this is done in the base index destructor)
* A segfault in the scheduler thread, which dereferences conman. (e.g. CheckForStaleTipAndEvictPeers)

23fbbb100f wallet: sum ancestors rather than taking max in output groups (Karl-Johan Alm)
Pull request description:
This is pointed out in https://github.com/bitcoin/bitcoin/pull/12257#discussion_r204549758.
Basically, the ancestors gives an indication as to how many ancestors the resulting transaction will have, which is more precise when summing up the values, rather than taking the maximum, since all the coins in the group will become ancestors if selected.

a1a998cf24 wallet: Fix backupwallet for multiwallets (Daniel Kraft)
Pull request description:
`backupwallet` was broken for multiwallets in their own directories (i.e. something like `DATADIR/wallets/mywallet/wallet.dat`). In this case, the backup would use `DATADIR/wallets/wallet.dat` as source file and not take the specific wallet's directory into account.
This led to either an error during the backup (if the wrong source file was not present) or would silently back up the wrong wallet; especially the latter behaviour can be quite bad for users.

4a43306a4f gui: Reject edit address dialog when key escape is pressed (João Barbosa)
f7a553177d gui: Add GUIUtil::ItemDelegate with keyEscapePressed signal (João Barbosa)
Pull request description:
Currently `EditAddressDialog` and `OptionsDialog` don't close when the escape key is pressed. The `QDataWidgetMapper` instances prevents closing the dialogs because the escape key is used to reset the widgets values. More details and workarounds in https://stackoverflow.com/a/51487847 and http://qtramblings.blogspot.com/2010/10/qdatawidgetmapper-annoyances.html.
The adopted solution is different from the above references. It turns out that `QDataWidgetMapper::setItemDelegate` sets the event filter for all mapped widgets. So in this PR the mapper's delegate are changed to a custom `GUIUtil::ItemDelegate` that offers the signal `keyEscapePressed`, which is connected to the `QDialog::reject` slot.
Note that the installed event filter lets all events pass, so the current behaviour isn't changed, meaning that widgets values are reset in addition to closing the dialog.

9994d01d8b Add Unit Test for SingleThreadedSchedulerClient (Jesse Cohen)
Pull request description:
As discussed in #13023 I've split this test out into a separate pr
This test (and documentation update) makes explicit the guarantee (previously undefined, but implied by the 'SingleThreaded' in `SingleThreadedSchedulerClient()`) - that callbacks pushed to the `SingleThreadedSchedulerClient()` obey the single threaded model for memory and execution - specifically, the callbacks are executed fully and in order, and even in cases where a subsequent callback is executed by a different thread, sequential consistency of memory for all threads executing these callbacks is maintained.
Maintaining memory consistency should make the api more developer friendly - especially for users of the validationinterface. To the extent that there are performance implications from this decision, these are not currently present in practice because all use of this scheduler happens on a single thread currently, furthermore the lock should guarantee consistency across callback executions even when callbacks are executed by multiple threads (as the test does).

04ce0d88ca Report when unknown config file options are ignored (Pieter Wuille)
Pull request description:
As reported by @satwo on IRC a few days ago, the current mechanism of treating unknown config file options as errors is problematic for options like `-rpcclienttimeout` which aren't defined for `bitcoind`.
A full solution would be to either make all binaries be aware of each other's options, or to permit config file options that only apply to specific binaries (`bitcoind`, `bitcoin-qt`, `bitcoin-cli`). Both of these seem too invasive to introduce for 0.17.
As a compromise, this PR makes it ignores those options, but still warn about it in the log file.

This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.
To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.
Refactors that were not required, but have been done anyways:
- The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.
- The `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

Pull request description:
This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.
It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).
For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).
Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.
Example: a node has four outputs linked to two addresses `A` and `B`:
* 1.0 btc to `A`
* 0.5 btc to `A`
* 1.0 btc to `B`
* 0.5 btc to `B`
The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
* 0.5 btc to `A` or `B` is picked
* 0.2 btc is output to `C`
* 0.3 - fee is output to (unique change address)
With `-avoidpartialspends`, the following will instead happen:
* Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
* 0.2 btc is output to `C`
* 1.3 - fee is output to (unique change address)
As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.
This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.
Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

This is a squashed commit that squashes the following commits:
This commit removes the `boost/algorithm/string/predicate.hpp` dependenc
from the project by replacing the function calls to `boost::algorithm::starts_with`
`boost::algorithm::ends_with` and `all` with respectively C++11'
`std::basic_string::front`, `std::basic_string::back`, `std::all_of` function calls
This commit replaces `boost::algorithm::is_digit` with a locale independent isdigi
function, because the use of the standard library's `isdigit` and `std::isdigit
functions is discoraged in the developer notes

793290f940 Net: Fixed a race condition when disabling the network. (lmanners)
Pull request description:
This change addresses a race condition where setnetworkactive=false wouldn't always disconnect all peers.
Before this change, the following could happen:
1. Thread A -- Begins connecting to a node.
2. Thread B -- Sets kNetworkActive=false and disconnects connected nodes.
3. Thread A -- Finishes connecting and adds node to list of connected nodes.
The node that was connected from Thread A remains connected and active,
even though kNetworkActive=false.
To fix the race, disconnections when kNetworkActive=false are now handled in the main network loop.

ac8a1d092e [RPC] Remove field in getblocktemplate help that has never been used (Conor Scott)
Pull request description:
[BIP 22 - getblocktemplate](https://github.com/bitcoin/bips/blob/master/bip-0022.mediawiki#Transactions%20Object%20Format) specifies an optional flag, `required` if the transaction must be in the block.
Luke's implementation #936 did not include this flag, and it was later added to the help description in #3246 (more than a year later) but the field was still never actually implemented. As far as I can tell, bitcoin core would have never actually included this in a `getblocktemplate` call, so it seems logical to remove it from the help description.
If I am missing something or this is considered harmless - I can close the PR.

1. mark "const" on ArgsManager::GetHelpMessage and IsArgKnown.
2. remove unused "error" argument from ArgsManager::IsArgKnown.
Firstly, I mark "const" on where it is possible to. It is mentioned
before (e.g. https://github.com/bitcoin/bitcoin/pull/13190#pullrequestreview-118823133).
And about 2nd change, ArgsManager::IsArgKnown was added at commit #4f8704d which was
merged at PR #13112. But from its beggining, "error" argument never be used.
I think it should be refactored.

This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.
Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.
This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

Pull request description:
Add error handling. Check return value of `ParseUInt32(...)` in `ParseHDKeypath(...)`.
`ParseUInt32(...)` returns `false` if the entire string could not be parsed or when an overflow or underflow occurred. In such case the uninitialized variable `number` would be used in the calculation of `path` (prior to this commit).
An example key path triggering this is `m/0/4294967296`:
```
ParseHDKeypath("m/0/4294967296", keypath);
```
`4294967296` is `1` + `0xFFFFFFFF` (`uint32_t` max: `4294967295`).

Pull request description:
This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.
BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.
This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.
***
Many RPCs have been added to handle PSBTs.
`walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.
`walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`
`decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`
`combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`
`finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.
`createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.
`convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.

This supersedes #12136

Alternative to #9152.
This takes `<n>` pubkeys and optionally `<n>` xpubs (together with a definable lookup windows where the default is 0-1000) and looks up common scripts in the UTXO set of all given or derived keys.
The output will be an array similar to `listunspent`. That array is compatible with `createrawtransaction` as well as with `signrawtransaction`.
This makes it possible to prepare sweeps and have them signed in a secure (cold) space.
