In eba1ba9 (maintenance: `git maintenance run` learned
`--scheduler=<scheduler>`, 2021-09-04), we introduced the ability to
specify a scheduler explicitly. This led to some extra checks around
whether an alternative scheduler was available. This added the
functionality of removing background maintenance from schedulers other
than the one selected.
On macOS, cron is technically available, but running 'crontab' triggers
a UI prompt asking for special permissions. This is the major reason why
launchctl is used as the default scheduler. The is_crontab_available()
method triggers this UI prompt, causing user disruption.
Remove this disruption by using an #ifdef to prevent running crontab
this way on macOS. This has the unfortunate downside that if a user
manually selects cron via the '--scheduler' option, then adjusting the
scheduler later will not remove the schedule from cron. The
'--scheduler' option ignores the is_available checks, which is how we
can get into this situation.
Extract the new check_crontab_process() method to avoid making the
'child' variable unused on macOS. The method is marked MAYBE_UNUSED
because it has no callers on macOS.

Cygwin emulates Unix sockets by writing files with custom contents and
then marking them as system files.
The tricky problem is that while the file is written and its `system`
bit is set, it is still identified as a file. This caused test failures
when Git is too fast looking for the Unix sockets and then complains
that there is a plain file in the way.
Let's work around this by adding a delayed retry loop, specifically for
Cygwin.

Revert the parse_options() prototype change in my recent
352e761388 (parse-options.[ch]: consistently use "enum
parse_opt_result", 2021-10-08) was incorrect. The parse_options()
function returns the number of argc elements that haven't been
processed, not "enum parse_opt_result".

As well as checking that the relevant functionality is available, the
GPGSSH prerequisite check creates the SSH keys that are used by the test
functions it gates. If these keys are created in a directory that
has a default Access Control List, the key files can inherit those
permissions.
This can result in a scenario where the private keys are created
successfully, so the prerequisite check passes and the tests are run,
but the key files have permissions that are too permissive, meaning
OpenSSH will refuse to load them and the tests will fail.
To avoid this happening, before creating the keys, clear any default ACL
set on the directory that will contain them. This step allowed to fail;
if setfacl isn't present, that's a very likely indicator that the
filesystem in question simply doesn't support default ACLs.

This fix corrects an issue found in the `dockerized(pedantic, fedora)` CI
build, first appearing after the introduction of a new version of the Fedora
docker image version. This image includes a version of `glibc` with the
attribute `__attr_access_none` added to `pthread_setspecific` [1], the
implementation of which only exists for GCC 11.X - the version included in
the Fedora image. The attribute requires that the pointer provided in the
second argument of `pthread_getspecific` must, if not NULL, be a pointer to
a valid object. In the usage in `async_die_is_recursing`, `(void *)1` is not
valid, causing the error.
This fix imitates a workaround added in SELinux [2] by using the pointer to
the static `async_die_counter` itself as the second argument to
`pthread_setspecific`. This guaranteed non-NULL, valid pointer matches the
intent of the current usage while not triggering the build error.

baf8ec8d3a (rebase -r: don't write .git/MERGE_MSG when
fast-forwarding, 2021-08-20) stopped reading the author script in
run_git_commit() when rewording a commit. This is normally safe
because "git commit --amend" preserves the authorship. However if the
user passes "--committer-date-is-author-date" then we need to read the
author date from the author script when rewording. Fix this regression
by tightening the check for when it is safe to skip reading the author
script.

This reverts the change from ed49584 (dir: fix pattern matching on dirs,
2021-09-24), which claimed to fix a directory-matching problem without a
test case. It turns out to _create_ a bug, but it is a bit subtle.
The bug would have been revealed by the first of two tests being added to
t0008-ignores.sh. The first uses a pattern "/git/" inside the a/.gitignores
file, which matches against 'a/git/foo' but not 'a/git-foo/bar'. This test
would fail before the revert.
The second test shows what happens if the test instead uses a pattern "git/"
and this test passes both before and after the revert.
The difference in these two cases are due to how
last_matching_pattern_from_list() checks patterns both if they have the
PATTERN_FLAG_MUSTBEDIR and PATTERN_FLAG_NODIR flags. In the case of "git/",
the PATTERN_FLAG_NODIR is also provided, making the change in behavior in
match_pathname() not affect the end result of
last_matching_pattern_from_list().
