48c845902a depends: fix qt determinism
Qt's configure grabs the path to xkb's data root during configure, but the
build changes in 5.8 apparently broke the handling for cross builds. As a
result, the string embedded in the binary depends on whether or not some files
are present in the builder's filesystem.

The "-xkb-config-root" configure setting is intended to allow manual overriding
but it is also broken. See: https://bugreports.qt.io/browse/QTBUG-60005

This has since been fixed upstream, so just hard-code the path for now. We can
drop this patch when we bump to a fixed Qt.

Also, fix the "-qt-xkbcommon-x11" config param which was renamed. This does not
appear to affect build results, presumably because auto-detection is working,
but it does not hurt to be explicit.

Fix PSBT deserialization of 0-input transactions
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.

Also always serialize the unsigned transaction as a non-witness transaction.

Merge #13054: tests: Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.
68400d8b96 tests: Use explicit imports (practicalswift)

Pull request description:

  Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.

  Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.

  An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Pull request description:

  Currently,  the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.

  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.

Merge #13666: Always create signatures with Low R values
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.

Pull request description:

  ### qa: Close stdout and stderr file when node stops

  Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.

  Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)

  ### qa: Run gen_rpcauth with sys.executable

  Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)

  ###   qa: Use files for stdout/stderr to support Windows

  It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.

Merge #13927: rpc: Use pushKV in some new PSBT RPCs
227d27e70c Use pushKV in some new PSBT RPCs. (Daniel Kraft)

Pull request description:

  Most of the code uses `UniValue::pushKV` where appropriate, but some new RPC code related to PSBTs did not.  This fixes those places - after this change, there are no remaining source files I could find that contain `push_back(Pair(`.

Merge #13924: tests: Simplify comparison in rpc_blockchain.py
1f87c372b5 Simplify comparison in rpc_blockchain.py. (Daniel Kraft)

Pull request description:

  The test for `gettxoutsetinfo` in `rpc_blockchain.py` verifies that the result is the same as before after invalidating and reconsidering a block.  The comparison has to exclude the `disk_size` field, though, as it is not deterministic.

  Instead of comparing all the other fields for equality, this change explicitly removes the `disk_size` field and then compares the full objects.  This makes the intent more explicit (compare everything except for `disk_size`, not compare just a given list of fields) and also the code simpler.

Merge #13907: Introduce a maximum size for locators.
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.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used
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.

18dfea0dd0 Always create 70 byte signatures with low R values
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.
