43811e6338 Fix PSBT deserialization of 0-input transactions (Andrew Chow)
Pull request description:
0-input transactions can be ambiguously deserialized as being witness transactions. Since the unsigned transaction is never serialized as a witness transaction as it has no witnesses, we should always deserialize it as a non-witness transaction and set the serialization flags as such.
When a transaction is serliazed for the non-witness-utxo, it is always a valid network transaction and thus it should be always be deserialized as a witness transaction and the deserialzation flags are set as such.

as witness.

fa5ce27385 ui: Compile boost:signals2 only once (MarcoFalke)
Pull request description:
ui is one of the modules that poison other modules with `boost/signals2` headers. This moves the include to the cpp file and uses a forward declaration in the header.
Locally this speeds up the incremental build (building everything that uses the ui module) with gcc by ~5% for me. Gcc uses ~5% less memory.
Would be nice if someone could verify the numbers roughly.
I presume the improvements will be more pronounced if the other models would stop exposing the boost header as well.

This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

18f690ec2f wallet: shuffle coins before grouping, where warranted (Karl-Johan Alm)
Pull request description:
Coins are randomly shuffled in coin selection to avoid unintentional privacy leaks regarding the user's coin set. For the case where a user has a lot of coins with the same destination, these will be grouped into groups of 10 *before* the shuffling.
It is unclear whether this has any implications at all, but this PR plugs the potential issue, if there ever is one, by shuffling the coins before they are grouped.

The `help2man` parses a string containing two spaces between words with an issue:
it gives out `.TP` and `.IP` commands instead of a single `.IP` command.
Removing an extra space fixes this issue.
Currently the `-help` output for the `-stdin` option looks without any issue due to eliminating
of two spaces between words by a `FormatParagraph` call for this particular case.
For consistency and preventing from future regressions extra spaces have been removed from the both lines.
The redundant `strprintf` call has been removed aswell.
Make sure that translations are synchronized with transifex before the
branch-off point to minimize the difference and prevent duplicate work.

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)

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)

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.

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.

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).

247d5740d2 Ignore unknown config file options for now (Pieter Wuille)
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.

fa5ed4f8d2 refactor: Avoid locking tx pool cs thrice (MarcoFalke)
Pull request description:
`addUnchecked` is (outside the tests) only called by ATMP, which already takes the tx pool read lock. So locking it twice more in both `addUnchecked` methods seems redundant.
Similarly `CalculateMemPoolAncestors` is (beside once in the wallet) only called in contexts, where the tx pool lock is already taken. So remove the lock there as well.

All but one call to GetBlocksToMaturity is testing it relative to 0
for the purposes of determining whether the coinbase tx is immature.
In such case, the value greater than 0 implies that the tx is coinbase,
so there is no need to separately test that status.
This names the concept for easy singular use.

e3245f2e7b Removes Boost predicate.hpp dependency (251)
Pull request description:
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.
