Use `UniqueLock` directly. Type deduction works just fine from the first
argument to the constructor of `UniqueLock`, so there is no need to
repeat
```cpp
UniqueLock<typename std::remove_reference<typename std::remove_pointer<decltype(cs)>::type>::type>
```
five times in the `LOCK` macros. Just `UniqueLock` suffices.
Use `MutexType` instead of `Mutex` for the template parameter of
`UniqueLock` because there is already a class named `Mutex` and the
naming overlap is confusing. `MutexType` is used elsewhere in `sync.h`.
8891949bdc index: Improve BaseIndex::BlockUntilSyncedToCurrentChain reliability (Ryan Ofsky)
Pull request description:
Since commit f08c9fb0c6 from PR https://github.com/bitcoin/bitcoin/pull/21726, index `BlockUntilSyncedToCurrentChain` behavior has been less reliable, and there has also been a race condition in the `coinstatsindex_initial_sync` unit test.
It seems better for `BlockUntilSyncedToCurrentChain` to actually wait for the last connected block to be fully processed, than to be able to return before prune locks are set, so this switches the order of `m_best_block_index = block;` and `UpdatePruneLock` statements in `SetBestBlockIndex` to make it more reliable.
Also since commit f08c9fb0c6, there has been a race condition in the `coinstatsindex_initial_sync` test. Before that commit, the atomic index best block pointer `m_best_block_index` was updated as the last step of `BaseIndex::BlockConnected`, so `BlockUntilSyncedToCurrentChain` could safely be used in tests to wait for the last `BlockConnected` notification to be finished before stopping and destroying the index. But after that commit, calling `BlockUntilSyncedToCurrentChain` is no longer sufficient, and there is a race between the test shutdown code which destroys the index object and the new code introduced in that commit calling `AllowPrune()` and `GetName()` on the index object. Reproducibility instructions for this are in https://github.com/bitcoin/bitcoin/issues/25365#issuecomment-1259744133
This commit fixes the `coinstatsindex_initial_sync` race condition, even though it will require an additional change to silence TSAN false positives, https://github.com/bitcoin/bitcoin/pull/26188, after it is fixed. So this partially addresses but does not resolve the bug reporting TSAN errors https://github.com/bitcoin/bitcoin/issues/25365.
There is no known race condition outside of test code currently, because the bitcoind `Shutdown` function calls `FlushBackgroundCallbacks` not `BlockUntilSyncedToCurrentChain` to safely shut down.

b85af25f87 refactor: mempool: add MemPoolLimits::NoLimits() (stickies-v)
Pull request description:
Mempool currently considers 4 limits regarding ancestor and descendant count and size, which get passed around between functions quite a bit. This PR uses `CTxMemPool::Limits` introduced in https://github.com/bitcoin/bitcoin/pull/25290 to simplify those signatures and callsites.
The purpose of this PR is to improve readability and maintenance, without behaviour change.
As noted in the first commit "refactor: mempool: change MemPoolLimits members to uint", we currently have an underflow issue where a user could pass a negative `-limitancestorsize`, which is eventually cast to an unsigned integer. This behaviour already exists. Because it's orthogonal and to minimize scope, I think this should be fixed in a separate PR.

From Russ Yanofsky:
"Agree with all of Marco's points here and think this should be updated
If havePrune and hasAssumedValidChain are both true, better to show
havePrune error message. Assumed-valid error message is vague and not
very actionable. Would suggest "Error loading wallet. Wallet requires
blocks to be downloaded, and software does not currently support loading
wallets while blocks are being downloaded out of order though assumeutxo
snapshots. Wallet should be able to load successfully after node sync
reaches height {block_height}"

Help from `bitcoind -h` states that conf can only be used from the commandline.
However, if conf is set in a bitcoin.conf file, it is ignored but there is no error.
Show an error to user if conf is set in a .conf file and prompt them to use
`includeconf` if they wish to specify additional config files.
Adds `IsConfSupported` function to allow for easily adding conf options
to disallow or throw warnings for.
Instead of having an entire TaprootBuilder which may or may not be
complete, and could potentially have future changes that interact oddly
with taproot tree tuples, have m_tap_tree be just the tuples.
When needed in other a TaprootBuilder for actual use, the tuples will be
added to a a TaprootBuilder that, in the future, can take in whatever
other data is needed as well.
Merging should be checking that the current PSBTOutput doesn't have a
taptree and the other one's is copied over. The original merging had
this inverted and would remove m_tap_tree if the other did not have it.

2147483647 is the maximum positive value of a signed int32, and - currently -
the maximum value that the deriveaddresses bitcoin RPC call accepts as
derivation index due to its input validation routines.
Before this change, when the derivation index (and thus range_end) reached
std::numeric_limits<int_32_t>::max(), the "i" variable in the for cycle (which
is declared as int, and as such 32 bits in size on most platforms) would be
incremented at the end of the first iteration and then warp back to
-2147483648. This caused SIGABRT in bitcoind and a core dump.
This change assigns "i" an explicit size of 64 bits on every platform,
sidestepping the problem.
Fixes#26274.
Check `port` options for invalid values (ports are parsed as uint16, so
in practice values >65535 are invalid; port 0 is undefined and therefore
considered invalid too). This allows for an early rejection of faulty
values and an supplying an informative message to the user.
Splits tests in `feature_proxy.py` to cover both invalid `hostname`
and `port` values.
Adds a release-note as previously valid `-port` and `-rpcport` values
can now result in errors.
Forward the validation of the port from `ParseUInt16(...)`.
Consider port 0 as invalid.
Add suitable test for the `SplitHostPort` function.
Add doxygen description to the `SplitHostPort` function.

During connection setup for a peer, getpeerinfo returns "version": 0, "subver": ""
and the GUI Peers window displays 0 and an empty field, respectively.
Give these fields the same behavior as the other fields in the GUI Peers window:
display the fallback value in src/qt/forms/debugwindow.ui (i.e. "N/A") until a
valid result is available after the peer connection completes.
The (100, 1000000, 1000, 1000000) limits are arbitrarily high and
don't restrict anything, they are just meant to calculate ancestors
properly. Using NoLimits() makes this intent more clear and simplifies
the code.
Simplifies function signatures by removing repetition of all the
ancestor/descendant limits, and increases readability by being
more verbose by naming the limits, while still reducing the LoC.
There are quite a few places in the codebase that require us to
construct a CTxMemPool without limits on ancestors and descendants.
This helper function allows us to get rid of all that duplication.

Moving the heavy (Boost) mempool code out of fuzz/util.h. Means that (for ex) a crypto_common fuzz unit doesn't need to care about seeing endless Boost headers. This results in a ~10% speedup (for me) when compiling the fuzz tests. Your results may vary.
