fafbf8acf4 Make G_FUZZING constexpr, require -DBUILD_FOR_FUZZING=ON to execute a fuzz target (MarcoFalke)
fae3cf0ffa ci: Temporarily disable macOS/Windows fuzz step (MarcoFalke)
Pull request description:
`g_fuzzing` is used inside `Assume` at runtime, causing significant overhead in hot paths. See https://github.com/bitcoin/bitcoin/issues/31178
One could simply remove the `g_fuzzing` check from the `Assume`, but this would make fuzzing a bit less useful. Also, it would be unclear if `g_fuzzing` adds a runtime overhead in other code paths today or in the future.
Fix all issues by making `G_FUZZING` equal to the build option `BUILD_FOR_FUZZING`, and for consistency in fuzzing, require it to be set when executing any fuzz target.
Fixes https://github.com/bitcoin/bitcoin/issues/31178
Temporarily this drops fuzzing from two CI tasks, but they can be re-added in a follow-up with something like https://github.com/bitcoin/bitcoin/pull/31073

davidgumberg:
I still ACK fafbf8acf4 for fixing the regression measured in #31178.
ryanofsky:
Code review ACK fafbf8acf4 but approach -0, because this approach means libraries built for fuzz testing do not function correctly if used in a release, and libraries built for releases are mostly useless for fuzz testing. So I would like to at least consider other solutions to this problem even if we go with this one.

The ci "test-each-commit" job fetches the PR branch being tested with a depth of (# of commits in PR + 2), and then tries to run tests on commits after the most recent merge commit.
When a PR is opened against a bitcoin core branch, a merge commit is always guaranteed to exist within the fetch depth, because bitcoin core branches always point at merge commits.
However, in fork repositories, pull requests can be opened based on other branches that don't contain recent merge commits, and this will currently cause git rev-list to fail with fatal: bad revision '^^@'.
Work around this problem by not requiring a recent merge commit, and just testing on all fetched commits if a merge commit can't be found.

9eea51d905 ci: move Asan / LSan / USDT job to Github Actions (Max Edwards)
4b527fa93b ci: add IPV6 network to ci container (Max Edwards)
Pull request description:
PR for moving the ASAN + LSAN + USDT + friends job to github actions from Cirrus.
The motivation for this PR is that this task needs a full VM (or bare metal) to function, because of the tracepoints. It can not run in a container on an arbitrary Linux, because the outside machine must exactly match the specification of the distro used in the CI task config. This requires more maintenance for the persistent worker, and I think moving to GHA will reduce the maintenance burden, or at least make it possible for anyone to work on.
Also, it makes it easier to run the task on forks (bitcoin-inquisition, bitcoin-knots, devel forks, ...) without having to set-up a real machine.

GHA Windows images previously had multiple VC Build Tools installed,
which required specifying the `VCPKG_PLATFORM_TOOLSET_VERSION`
explicitly to avoid linker errors. This issue has been resolved as per
https://github.com/actions/runner-images/issues/9701.

Pull request description:
Extraction of just printing powershell version from closed PR: https://github.com/bitcoin/bitcoin/pull/29581
See https://github.com/bitcoin/bitcoin/pull/29581#issuecomment-1984212990 for the cause of a CI failure which was a powershell update.
This PR will make it easier to notice in the future that PS has changed.

ACK 115c283516. We still use PowerShell in some steps of the "Win64 native" CI job.

Homebrew attempts to check for outdated dependents or those with broken
linkage. Such behavior might lead to failures when Homebrew updates them
on old macOS images.
This change prevents such behavior.
The GHA VS installation includes its own vcpkg package manager, which is
available since VS 17.6. This change avoids any ambiguity about which
copy of vcpkg we run.
