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.
115c283516 ci: add print of powershell version to win64 job (Max Edwards)
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Homebrew attempts to check for outdated dependents or those with broken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.
88c8e3a0e4 github actions: Fix test-one-commit when parent of head is merge commit (Ryan Ofsky)
Pull request description:
Instead of figuring out the commit *after* the last merge and rebasing on that with a ~1 suffix, just figure out the last merge commit directly and rebase on it. This way, if HEAD happens to be a merge commit, the rebase just succeeds immediately without blank variables or errors.
Explanation of the problem from https://github.com/bitcoin/bitcoin/pull/28497#issuecomment-1743430631:
> The problem is that the PR only contains a one commit after the last merge, so the job _should_ be skipped, but the `pull_request.commits != 1` check is not smart enough to skip it because the PR is based on another PR and has merge ancestor commits. So specifically what happens is that after HEAD~ is checked out, the new HEAD is a merge commit, so the range `$(git log --merges -1 --format=%H)..HEAD` is equivalent to HEAD..HEAD, which is empty, so the `COMMIT_AFTER_LAST_MERGE` variable is empty and the rebase command fails.
Note: In the current version of this PR, the "test each commit" job is skipped, because this PR only contains a single commit. But I manually verified the code works in earlier versions of the PR that included dummy commits.

fa5356cd49 ci: Limit test-each-commit to --max-count=6 (MarcoFalke)
fafcd2e9ef ci: Add test-each-commit task (MarcoFalke)
Pull request description:
Currently, if a pull request has more than one commit, previous commits may fail to compile, or may fail the tests. This is problematic, because it breaks git-bisect, or worse.
Fix this by adding a CI task for this.
