Update 'stash' to use 'merge_ort_nonrecursive()' to apply a stash to the
current working tree. When 'git stash apply' was converted from its shell
script implementation to a builtin in 8a0fc8d19d (stash: convert apply to
builtin, 2019-02-25), 'merge_recursive_generic()' was used to merge a stash
into the working tree as part of 'git stash (apply|pop)'. However, with the
single merge base used in 'do_apply_stash()', the commit wrapping done by
'merge_recursive_generic()' is not only unnecessary, but misleading (the
*real* merge base is labeled "constructed merge base"). Therefore, a
non-recursive merge of the working tree, stashed tree, and stash base tree
is more appropriate.
There are two options for a non-recursive merge-then-update-worktree
function: 'merge_trees()' and 'merge_ort_nonrecursive()'. Use
'merge_ort_nonrecursive()' to align with the default merge strategy used by
'git merge' (6a5fb96672 (Change default merge backend from recursive to ort,
2021-08-04)) and, because merge-ort does not operate in-place on the index,
avoid unnecessary index expansion. Update tests in 't1092' verifying index
expansion for 'git stash' accordingly.

When the index read in 'do_read_index()' does not exist on-disk, mark the
index "sparse" if the executing command does not require a full index and
sparse index is otherwise enabled.
Some commands (such as 'git stash -u') implicitly create a new index (when
the 'GIT_INDEX_FILE' variable points to a non-existent file) and perform
some operation on it. However, when this index is created, it isn't created
with the same sparsity settings as the repo index. As a result, while these
indexes may be sparse during the operation, they are always expanded before
being written to disk. We can avoid that expansion by defaulting the index
to "sparse", in which case it will only be expanded if the full index is
needed.
Note that the function 'set_new_index_sparsity()' is created despite having
only a single caller because additional callers will be added in a
subsequent patch.

Expose 'is_sparse_index_allowed()' publicly so that it may be used by
callers outside of 'sparse-index.c'. While no such callers exist yet, it
will be used in a subsequent commit.

Enable sparse index in 'git stash' by disabling
'command_requires_full_index'.
With sparse index enabled, some subcommands of 'stash' work without
expanding the index, e.g., 'git stash', 'git stash list', 'git stash drop',
etc. Others ensure the index is expanded either directly (as in the case of
'git stash [pop|apply]', where the call to 'merge_recursive_generic()' in
'do_apply_stash()' triggers the expansion), or in a command called
internally by stash (e.g., 'git update-index' in 'git stash -u'). So, in
addition to enabling sparse index, add tests to 't1092' demonstrating which
variants of 'git stash' expand the index, and which do not.
Finally, add the option to skip writing 'untracked.txt' in
'ensure_not_expanded', and use that option to successfully apply stashed
untracked files without a conflict in 'untracked.txt'.

Add tests verifying expected 'git stash' behavior in
't1092-sparse-checkout-compatibility'. These cases establish the expected
behavior of 'git stash' in a sparse-checkout and verify consistency both
with and without a sparse index. Although no sparse index compatibility has
been integrated into 'git stash' yet, the tests are all 'expect_success' -
we don't want the cone-mode sparse-checkout behavior to change depending on
whether it is using a sparse index or not. Therefore, we expect these tests
to continue passing once sparse index is integrated with 'git stash'.
Additionally, add performance test cases for 'git stash' both with and
without untracked files. Note that, unlike the other tests in
'p2000-sparse-operations.sh', the tests added for 'stash' are combination
operations. This is done to ensure the stash/unstash is not blocked by the
modification of '$SPARSE_CONE/a' performed as part of 'test_perf_on_all'.

A couple of work around for CI breaking warnings from gcc 12.
* cb/buggy-gcc-12-workaround:
config.mak.dev: alternative workaround to gcc 12 warning in http.c
config.mak.dev: workaround gcc 12 bug affecting "pedantic" CI job
This provides a "no code change needed" option to the "fix" currently
queued as part of ab/http-gcc-12-workaround and therefore should be
reverted once that gets merged.

Originally noticed by Peff[1], but yet to be corrected[2] and planned to
be released with Fedora 36 (scheduled for Apr 19).
dir.c: In function ‘git_url_basename’:
dir.c:3085:13: error: ‘memchr’ specified bound [9223372036854775808, 0] exceeds maximum object size 9223372036854775807 [-Werror=stringop-overread]

Fedora is used as part of the CI, and therefore that release will trigger
failures, unless the version of the image used is locked to an older
release, as an alternative.
Restricting the flag to the affected source file, as well as implementing
an independent facility to track these workarounds was specifically punted
to minimize the risk of introducing problems so close to a release.
This change should be reverted once the underlying gcc bug is solved and
which should be visible by NOT triggering a warning, otherwise.

We do not have to guess how common the mistake the change targets is
when describing it. Such an argument may be good while proposing a
change, but does not quite belong in the record of what has already
happened, i.e. a release note.

This reverts commit 2a0cafd464,
as it expects a working "a ref deletion must produce a single
transaction, not one for loose and another for packed" topic,
which we do not have.
With the addition of the safe.directory in 8959555ce
(setup_git_directory(): add an owner check for the top-level directory,
2022-03-02) released in v2.35.2, we are receiving feedback from a
variety of users about the feature.
Some users have a very large list of shared repositories and find it
cumbersome to add this config for every one of them.
In a more difficult case, certain workflows involve running Git commands
within containers. The container boundary prevents any global or system
config from communicating `safe.directory` values from the host into the
container. Further, the container almost always runs as a different user
than the owner of the directory in the host.
To simplify the reactions necessary for these users, extend the
definition of the safe.directory config value to include a possible '*'
value. This value implies that all directories are safe, providing a
single setting to opt-out of this protection.
Note that an empty assignment of safe.directory clears all previous
values, and this is already the case with the "if (!value || !*value)"
condition.

It seems that nothing is ever checking to make sure the safe directories
in the configs actually have the key safe.directory, so some unrelated
config that has a value with a certain directory would also make it a
safe directory.

It is difficult to change the ownership on a directory in our test
suite, so insert a new GIT_TEST_ASSUME_DIFFERENT_OWNER environment
variable to trick Git into thinking we are in a differently-owned
directory. This allows us to test that the config is parsed correctly.
