In the preceding commit a free() of uninitialized memory regression in
96e41f58fe1 (fsck: report invalid object type-path combinations,
2021-10-01) was fixed, but we'd still have an issue with leaking
memory from fsck_loose(). Let's fix that issue too.
That issue was introduced in my 31deb28f5e0 (fsck: don't hard die on
invalid object types, 2021-10-01). It can be reproduced under
SANITIZE=leak with the test I added in 093fffdfbec (fsck tests: add
test for fsck-ing an unknown type, 2021-10-01):
./t1450-fsck.sh --run=84 -vixd
In some sense it's not a problem, we lost the same amount of memory in
terms of things malloc'd and not free'd. It just moved from the "still
reachable" to "definitely lost" column in valgrind(1) nomenclature[1],
since we'd have die()'d before.
But now that we don't hard die() anymore in the library let's properly
free() it. Doing so makes this code much easier to follow, since we'll
now have one function owning the freeing of the "contents" variable,
not two.
For context on that memory management pattern the read_loose_object()
function was added in f6371f92104 (sha1_file: add read_loose_object()
function, 2017-01-13) and subsequently used in c68b489e564 (fsck:
parse loose object paths directly, 2017-01-13). The pattern of it
being the task of both sides to free() the memory has been there in
this form since its inception.

This reverts commit f45022dc2fd692fd024f2eb41a86a66f19013d43,
as this is like breakage in the traversal more likely. In a
history with 10 single strand of pearls,
1-->2-->3--...->7-->8-->9-->10
asking "rev-list --unsorted-input 1 10 --not 9 8 7 6 5 4" fails to
paint the bottom 1 uninteresting as the traversal stops, without
completing the propagation of uninteresting bit starting at 4 down
through 3 and 2 to 1.

Fix a regression introduced in my 96e41f58fe1 (fsck: report invalid
object type-path combinations, 2021-10-01). When fsck-ing blobs larger
than core.bigFileThreshold, we'd free() a pointer to uninitialized
memory.
This issue would have been caught by SANITIZE=address, but since it
involves core.bigFileThreshold, none of the existing tests in our test
suite covered it.
Running them with the "big_file_threshold" in "environment.c" changed
to say "6" would have shown this failure, but let's add a dedicated
test for this scenario based on Han Xin's report[1].
The bug was introduced between v9 and v10[2] of the fsck series merged
in 061a21d36d8 (Merge branch 'ab/fsck-unexpected-type', 2021-10-25).

The way Cygwin emulates a unix-domain socket, on top of which the
simple-ipc mechanism is implemented, can race with the program on
the other side that wants to use the socket, and briefly make it
appear as a regular file before lstat(2) starts reporting it as a
socket. We now have a workaround on the side that connects to a
unix domain socket.

"git pull --ff-only" and "git pull --rebase --ff-only" should make
it a no-op to attempt pulling from a remote that is behind us, but
instead the command errored out by saying it was impossible to
fast-forward, which may technically be true, but not a useful thing
to diagnose as an error. This has been corrected.

The "-Y find-principals" option of ssh-keygen seems to be broken in
Debian's openssh-client 1:8.7p1-1, whereas it works fine in 1:8.4p1-5.
This causes several failures for GPGSSH tests. We fulfill the
prerequisite because generating the keys works fine, but actually
verifying a signature causes results ranging from bogus results to
ssh-keygen segfaulting.
We can find the broken version during the prereq check by feeding it
empty input. This should result in it complaining to stderr, but in the
broken version it triggers the segfault, causing the GPGSSH tests to be
skipped.

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.

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.
