All the Perforce tests are free of memory leaks. This went unnoticed
because most folks do not have p4 and p4d installed on their computers.
Consequently, given that the prerequisites for running those tests
aren't fulfilled, `TEST_PASSES_SANITIZE_LEAK=check` won't notice that
those tests are indeed memory leak free.
Mark those tests accordingly.

Update our Perforce version from r21.2 to r23.2. Note that the updated
version is not the newest version. Instead, it is the last version where
the way that Perforce is being distributed remains the same as in r21.2.
Newer releases stopped distributing p4 and p4d executables as well as
the macOS archives directly and would thus require more work.

Some of the tests in t98xx modify the Perforce depot in ways that the
tool wouldn't normally allow. This is done to test behaviour of git-p4
in certain edge cases that we have observed in the wild, but which
should in theory not be possible.
Naturally, modifying the depot on disk directly is quite intimate with
the tool and thus prone to breakage when Perforce updates the way that
data is stored. And indeed, those tests are broken nowadays with r23 of
Perforce. While a file revision was previously stored as a plain file
"depot/file,v", it is now stored in a directory "depot/file,d" with
compression.
Adapt those tests to handle both old- and new-style depot layouts.

When `core.maxTreeDepth` was originally introduced via be20128bfa (add
core.maxTreeDepth config, 2023-08-31), its default value was 4096.
There have since been a couple of updates to its default value that were
not reflected in the documentation for `core.maxTreeDepth`:
- 4d5693ba05 (lower core.maxTreeDepth default to 2048, 2023-08-31)
- b64d78ad02 (max_tree_depth: lower it for MSVC to avoid stack
overflows, 2023-11-01)
Commit 4d5693ba05 lowers the default to 2048 for platforms with smaller
stack sizes, and commit b64d78ad02 lowers the default even further when
Git is compiled with MSVC.
Neither of these changes were reflected in the documentation, which I
noticed while merging newer releases back into GitHub's private fork
(which contained the original implementation of `core.maxTreeDepth`).
Update the documentation to reflect what the platform-specific default
values are.

Commit 852a171018 (am: let command-line options override saved options,
2015-08-04) redirected a few "git am" invocations from /dev/zero, even
though it did not expect "am" to read the input. This was necessary at
the time because those tests used test_terminal, and as described in
18d8c26930 (test_terminal: redirect child process' stdin to a pty,
2015-08-04):
Note that due to the way the code is structured, the child's stdin
pseudo-tty will be closed when we finish reading from our stdin. This
means that in the common case, where our stdin is attached to /dev/null,
the child's stdin pseudo-tty will be closed immediately. Some operations
like isatty(), which git-am uses, require the file descriptor to be
open, and hence if the success of the command depends on such functions,
test_terminal's stdin should be redirected to a source with large amount
of data to ensure that the child's stdin is not closed, e.g.
test_terminal git am --3way </dev/zero
But we later dropped the use of test_terminal in 53ce2e3f0a (am: add
explicit "--retry" option, 2024-06-06). That commit dropped one of the
redirections from /dev/zero but not the other.
In theory the remaining one should not cause any problems, but it turns
out that at least one platform (NonStop) does not have /dev/zero at all.
We never noticed before because it also did not pass the TTY prereq,
meaning these tests were not run at all there until 53ce2e3f0a.
So let's drop the useless /dev/zero mention. There are others in the
test suite, but they are run only for tests marked with EXPENSIVE (so
not typically by default).

On Windows, Unix-like paths like `/bin/sh` make very little sense. In
the best case, they simply don't work, in the worst case they are
misinterpreted as absolute paths that are relative to the drive
associated with the current directory.
To that end, Git does not actually use the path `/bin/sh` that is
recorded e.g. when `run_command()` is called with a Unix shell
command-line. Instead, as of 776297548e (Do not use SHELL_PATH from
build system in prepare_shell_cmd on Windows, 2012-04-17), it
re-interprets `/bin/sh` as "look up `sh` on the `PATH` and use the
result instead".
This is the logic users expect to be followed when running `git var
GIT_SHELL_PATH`.
However, when 1e65721227 (var: add support for listing the shell,
2023-06-27) introduced support for `git var GIT_SHELL_PATH`, Windows was
not special-cased as above, which is why it outputs `/bin/sh` even
though that disagrees with what Git actually uses.
Let's fix this by using the exact same logic as `prepare_shell_cmd()`,
adjusting the Windows-specific `git var GIT_SHELL_PATH` test case to
verify that it actually finds a working executable.

In 776297548e (Do not use SHELL_PATH from build system in
prepare_shell_cmd on Windows, 2012-04-17), the hard-coded path to the
Unix shell was replaced by passing `sh` instead when executing Unix
shell scripts in Git.
This was done because the hard-coded path to the Unix shell is incorrect
on Windows because it not only is a Unix-style absolute path instead of
a Windows one, but Git uses the runtime prefix feature on Windows, i.e.
the correct path cannot be hard-coded.
Naturally, the `sh` argument will be resolved to the full path of said
executable eventually.
To help fixing the bug where `git var GIT_SHELL_PATH` currently does not
reflect that logic, but shows that incorrect hard-coded Unix-style
absolute path, let's resolve the full path to the `sh` executable early
in the `git_shell_path()` function so that we can use it in `git var`,
too, and be sure that the output is equivalent to what `run_command()`
does when it is asked to execute a command-line using a Unix shell.

Whether the full path to the MSYS2 Bash is specified using backslashes
or forward slashes, in either case the command-line arguments need to be
quoted in the MSYS2-specific manner instead of using regular Win32
command-line quoting rules.
In preparation for `prepare_shell_cmd()` to use the full path to
`sh.exe` (with forward slashes for consistency), let's teach the
`is_msys2_sh()` function about this; Otherwise 5580.4 'clone with
backslashed path' would fail once `prepare_shell_cmd()` uses the full
path instead of merely `sh`.
This patch relies on the just-introduced fix where `fspathcmp()` handles
backslashes and forward slashes as equivalent on Windows.

On Windows, the backslash is the directory separator, even if the
forward slash can be used, too, at least since Windows NT.
This means that the paths `a/b` and `a\b` are equivalent, and
`fspathcmp()` needs to be made aware of that fact.
Note that we have to override both `fspathcmp()` and `fspathncmp()`, and
the former cannot be a mere pre-processor constant that transforms calls
to `fspathcmp(a, b)` into `fspathncmp(a, b, (size_t)-1)` because the
function `report_collided_checkout()` in `unpack-trees.c` wants to
assign `list.cmp = fspathcmp`.
Also note that `fspatheq()` does _not_ need to be overridden because it
calls `fspathcmp()` internally.

This function differs from `strvec_push()` in that it takes ownership of
the allocated string that is passed as second argument.
This is useful when appending elements to the string array that have
been freshly allocated and serve no further other purpose after that.
Without declaring this function globally, call sites would allocate the
memory, only to have `strvec_push()` duplicate the string, and then the
first copy would need to be released. Having this function globally
avoids that kind of unnecessary work.

When an end-user runs "git push" with an empty string for the remote
repository name, e.g.
$ git push '' main
"git push" fails with a BUG(). Even though this is a nonsense request
that we want to fail, we shouldn't hit a BUG(). Instead we want to give
a sensible error message, e.g., 'bad repository'".
This is because since 9badf97c42 (remote: allow resetting url list,
2024-06-14), we reset the remote URL if the provided URL is empty. When
a user of 'remotes_remote_get' tries to fetch a remote with an empty
repo name, the function initializes the remote via 'make_remote'. But
the remote is still not a valid remote, since the URL is empty, so it
tries to add the URL alias using 'add_url_alias'. This in-turn will call
'add_url', but since the URL is empty we call 'strvec_clear' on the
`remote->url`. Back in 'remotes_remote_get', we again check if the
remote is valid, which fails, so we return 'NULL' for the 'struct
remote *' value.
The 'builtin/push.c' code, calls 'set_refspecs' before validating the
remote. This worked with empty repo names earlier since we would get a
remote, albeit with an empty URL. With the new changes, we get a 'NULL'
remote value, this causes the check for remote to fail and raises the
BUG in 'set_refspecs'.
Do a simple fix by doing remote validation first. Also add a test to
validate the bug fix. With this, we can also now directly pass remote to
'set_refspecs' instead of it trying to lazily obtain it.
