f974359e21 test: Add encodable PUSHDATA1 examples to feature_taproot (Greg Sanders)
Pull request description:
Inspired by discussion in https://github.com/bitcoin/bitcoin/pull/31640#issuecomment-2743492906 I made an example adding coverage I think is missing, with some extra commentary that might help future contributors (including myself when I forget how it works again).
Open for suggestions how we can make it more welcoming beyond this.

Pull request description:
The `FeeFrac` type represents a fraction, intended to be used for sats/vbyte or sats/WU. This PR adds functionality to evaluate that feerate for a given size, in order to obtain the fee it corresponds with (rounding down, or rounding up).
The motivation here is being able to do accurate feerate evaluations in cluster mempool block building heuristics (where rounding down is needed), but in principle this makes it possible to use `FeeFrac` as a more accurate replacement for `CFeeRate` (where for feerate estimation rounding up is desirable). Because of this, both rounding modes are implemented.
Unit tests are included for known-correct values, plus a fuzz test that verifies the result using `arith_uint256`.

Rather than use an ad-hoc reimplementation of wide multiplication inside the
fuzz test, reuse arith_uint256, which already has this. It's larger than what we
need here, but performance isn't a concern in this test, and it does what we need.
Since C++20, operator!= is implicitly defaulted using operator==, and
operator<, operator<=, operator>, and operator>= are defaulted using
operator<=>, so it suffices to just provide these two.
Remove the manual batch size estimation logic (`SizeEstimate()` method and `size_estimate` member) from `CDBBatch`.
Size is now determined solely by the `ApproximateSize()` method introduced in the previous commit, which delegates to the native LevelDB function.
The manual calculation is no longer necessary as LevelDB now provides this functionality directly, and the previous commit verified that the native function's results matched the manual estimation.
Assertions comparing the two methods are removed from `txdb.cpp`.
Co-authored-by: Wladimir J. van der Laan <laanwj@protonmail.com>
Serialized batch size can be queried via the underlying LevelDB implementation calling the native `leveldb::WriteBatch::ApproximateSize()`.
The previous manual calculation was added in e66dbde6d1 as part of https://github.com/bitcoin/bitcoin/pull/10195. At that time (April 2017), the version of LevelDB used by Bitcoin Core (and even the latest source) lacked a native function for this. LevelDB added this capability in 69e2bd224b, merged later that year.
The old manual estimation method (`SizeEstimate()`) is kept temporarily in this commit, and assertions are added in `txdb.cpp` to verify its results against `ApproximateSize()` during batch writes. This ensures the native function behaves as expected before removing the manual calculation in the subsequent commit.
The initialization of the manual `size_estimate` in `CDBBatch::Clear()` is corrected from `0` to `kHeader` (LevelDB's fixed batch header size).
This aligns the manual estimate with LevelDB's actual size immediately after clearing, fixing discrepancies that would otherwise be caught by tests in the next commit (e.g., `coins_tests`, `validation_chainstatemanager_tests`).
fadf8f078e test: Remove confusing and failing system time test (MarcoFalke)
Pull request description:
This was just added as a sanity check in fa013664ae by myself.
However, the test uses system time, so it may obviously (albeit rarely) fail.
Fix it by removing it.
Can be tested by running two bash loops at the same time:
`while ( ./bld-cmake/bin/test_bitcoin -t util_tests/util_time_GetTime ) ; do true ; done`
`while ( date -s "$(date -d 'now + 0.015 seconds' '+%Y-%m-%d %H:%M:%S.%3N')" && date -s "$(date -d 'now - 0.015 seconds' '+%Y-%m-%d %H:%M:%S.%3N')" ) ; do true ; done`
Eventually, it will fail:
```
test/util_tests.cpp(595): error: in "util_tests/util_time_GetTime": check ms_0 < GetTime<std::chrono::milliseconds>() has failed
test/util_tests.cpp(596): error: in "util_tests/util_time_GetTime": check us_0 < GetTime<std::chrono::microseconds>() has failed

Pull request description:
While generating `profraw` for fuzz tests using steps in [PR 32206](https://github.com/bitcoin/bitcoin/pull/32206) , the profraw was not being built at the desired location and only one `default.profraw` was being created which was being overwritten for multiple fuzz targets. This PR fixes that.

faa807bdf8 ci: Merge master in test-each-commit task (MarcoFalke)
Pull request description:
The `test-each-commit` task will often fail, when the CI config yaml is updated along with code changes.
This is because, GitHub seems to be merging the CI config on a fresh pull with the current target branch (`master`). However, the code changes are not.
A tedious workaround would be for every developer to rebase on every intermittent (https://github.com/bitcoin/bitcoin/issues/31946#issuecomment-2740911853) and non-intermittent CI issue.
However, fix this instead by merging with `master`.

There turned out to be a mismatch in the tx output counts which caused
'ConnectBlockMixedEcdsaSchnorr' benchmark to run slower than
'ConnectBlockAllEcdsa' and 'ConnectBlockAllSchnorr'. This commit makes
the tx output counts uniform across all benchmarks.
This commit also renames the 'taproot_tx' variable to 'tx' to reflect
that this variable represents a general tx and not just a taproot tx.
The new helper will be used to fix a crash in the
wallet migration process (watch-only, non-blank,
private keys disabled, empty wallet - no scripts
or addresses imported).

Add a class TorsStreamIsolationCredentialsGenerator that generates
unique credentials based on a randomly generated session prefix
and an atomic counter.
This makes sure that different launches of the application won't share
the same credentials, and thus circuits, even in edge cases.
Example with `-debug=proxy`:
```

Pull request description:
Was looking at my local coverage report, and noticed a few spots that will not or cannot be hit.
CountDistinctClusters, GetAncestorsUnion, and GetDescendantsUnion accept nullptrs, but the test harness never employs them. Disallow them.
We never call PullIn whenever there isn't staging, so just enforce that invariant via assertion.
Remaining places that are not covered:
1) Relinearize: Currently we seem to always start with a cold (not known to be optimal) cluster, and after one attempt at linearization result into something optimal. This means we never shortcircuit, nor run PostLinearization, nor store the quality as ACCEPTABLE. Reducing iterations causes these lines to be hit. sipa says he will take this on as varying the amount of iterations was meant to be done eventually anyways.
2) We never do a move assignment operator when the lvalue already has a `m_graph` (so we never call UnlinkRef) 3358b1d105/src/txgraph.cpp (L2097)
3) We never use the move constructor: 3358b1d105/src/txgraph.cpp (L2108)

With newly introduced libmultiprocess subtree, there's no need for depends
system to download and track changes to the upstream repository.
Note that adding the libmultiprocess subtree does not allow dropping
libmultiprocess packages from the depends build, because libmultiprocess
includes a code generation tool called mpgen, and in cross-compiled builds,
bitcoin core's cmake build system doesn't have access to a native toolchain and
can't build mpgen itself, so the depends system (or the native environment if
not using depends) needs to supply it.
Move parts of the int_get_build_id into a new int_get_build_properties
function. There is no change in behavior. This just organizes assignments
better so some build properties can be used to help compute build ids in the
next commit.
Without this change linter produces errors about:
- Use of std::filesystem the libmultiprocess example program.
- Use of locale-dependent functions in example program, in the build time code
generator, and in the runtime library for debug logging.
- Include guards not beginning with BITCOIN_
This change is technically not needed to add libmultiprocess as a subtree, but
it avoids a CI failure in followup PR #30975 which enables multiprocess build
option in more CI jobs. In that PR, several jobs fail due to the mptest
executable not being built by default, as reported

When ENABLE_IPC option is on, build with libmultiprocess subtree and
`add_subdirectory(src/ipc/libmultiprocess)` instead of external package
and `find_package(Libmultiprocess)` by default.
Behavior can be toggled with `WITH_EXTERNAL_LIBMULTIPROCESS` option. Using a
subtree should be more convenient for most bitcoin developers, but using an
external package is more convenient for developing in the libmultiprocess
repository.
The `WITH_EXTERNAL_LIBMULTIPROCESS` option is also used to avoid needing to
changing the depends build here. But in later commits, the depends build is
switched to use the add_subdirectory build as well.

Rename WITH_MULTIPROCESS to ENABLE_IPC, because ENABLE_IPC is a more accurate
name for the feature. It controls whether the src/ipc/ directory is built and
whether IPC features like -ipcbind, -ipcconnect, and -ipcfd are available. It
does NOT currently enable multiprocess features which are implemented in #10102
building on top of the IPC features. It will also no longer (as of the next
commit), control whether a find_package call is made so the "WITH_" prefix is
also inappropriate.
