There's no real value in doing it via commit for official GH actions. We
can keep using pinned commits for unofficial actions. It's hassle for no
gain.
Maybe going forward we can limit this further by only being paranoid
for the jobs with any access to tokens.

We discussed the name and it's less cognitive load to just call it '.bash'
so you don't have an immediate question about if bashisms are OK.

Unfortunately, UBSAN doesn't do this by default. See also the change
I made in Meson for this in October [0].

Using `--trace-children=yes` has a trade-off here, as it makes
`test_scripts.sh` pretty slow when calling various non-xz utilities.
But I also feel like it's not useless to have Valgrind used there and it's
not easy to exclude Valgrind just for that one test...
I did consider using AX_VALGRIND_CHECK [0][1] but I couldn't get it working
immediately with some conditionally-built tests and I wondered if it was
worth spending time on at least while we're debating xz's future build
system situation.

(cherry picked from commit 6c095a98fb)
The sandboxing on Linux now supports Landlock, which restricts all
supported filesystem actions after xz opens the files it needs. The
sandbox is only enabled when one file is input and we are writing to
standard out. With fsanitize=address,undefined, the instrumentation
needs to read additional files after the sandbox is in place. This
forces all xz based test to fail, so the sandbox must instead be
disabled.
Referencing actions by commit SHA in GitHub workflows guarantees you are using an immutable version. Actions referenced by tags and branches are more vulnerable to attacks, such as the tag being moved to a malicious commit or a malicious commit being pushed to the branch.
It's important to make sure the SHA's are from the original repositories and not forks.

ci_build.sh was updated to accept disabling of __attribute__ ifunc
and CLMUL. This will allow -fsanitize=address to pass because ifunc
is incompatible with -fsanitize=address. The CLMUL implementation has
optimizations that potentially read past the buffer and mask out the
unwanted bytes.
This test will only run on Autotools Linux.
Now, CMake will run similar feature disable tests that the Autotools
version did before. In order to do this without repeating lines in
ci.yml, it now makes sense to use the GitHub Workflow matrix to create
a loop.
The 32-bit build needs to be first so the configure cache only needs to
be reset one time. The 32-bit build sets the CFLAGS env variable, so any
build using that flag after will fail unless the cache is reset.
Disabling shared library generation and linking should help speed up the
runners. The shared library is still being tested in the 32 bit build
and the full feature.
Disabling nls is to check for any unexpected warnings or errors.
The old version used too many runners that resulted in unnecessary
dependency downloads. Now, the runners are reused for the different
configurations for each OS and build system.
The CI/CD workflow will only execute on Ubuntu and MacOS latest version.
The workflow will attempt to build with autotools and CMake and execute
the tests. The workflow will run for all pull requests and pushes done
to the master branch.
