When using "git-diff-tree" to get the tree diff for merge commits with
the diff format set to `remerge`, a bug is triggered as shown below:
$ git diff-tree -r --remerge-diff 363337e6eb363337e6eb
BUG: log-tree.c:1006: did a remerge diff without remerge_objdir?!?
This bug is reported by `log-tree.c:do_remerge_diff`, where a bug check
added in commit 7b90ab467a (log: clean unneeded objects during log
--remerge-diff, 2022-02-02) detects the absence of `remerge_objdir` when
attempting to clean up temporary objects generated during the remerge
process.
After some further digging, I find that the remerge-related diff options
were introduced in db757e8b8d (show, log: provide a --remerge-diff
capability, 2022-02-02), which also affect the setup of `rev_info` for
"git-diff-tree", but were not accounted for in the original
implementation (inferred from the commit message).
Elijah Newren, the author of the remerge diff feature, notes that other
callers of `log-tree.c:log_tree_commit` (the only caller of
`log-tree.c:do_remerge_diff`) also exist, but:
`builtin/am.c`: manually sets all flags; remerge_diff is not among them
`sequencer.c`: manually sets all flags; remerge_diff is not among them
so `builtin/diff-tree.c` really is the only caller that was overlooked
when remerge-diff functionality was added.
This commit resolves the crash by adding `remerge_objdir` setup logic to
`builtin/diff-tree.c`, mirroring `builtin/log.c:cmd_log_walk_no_free`.
It also includes the necessary cleanup for `remerge_objdir`.

When compacting tables, it may happen that we want to compact a set of
tables which are already locked by a concurrent process that compacts
them. In the case where we wanted to perform a full compaction of all
tables it is sensible to bail out in this case, as we cannot fulfill the
requested action.
But when performing auto-compaction it isn't necessarily in our best
interest of us to abort the whole operation. For example, due to the
geometric compacting schema that we use, it may be that process A takes
a lot of time to compact the bulk of all tables whereas process B
appends a bunch of new tables to the stack. B would in this case also
notice that it has to compact the tables that process A is compacting
already and thus also try to compact the same range, probably including
the new tables it has appended. But because those tables are locked
already, it will fail and thus abort the complete auto-compaction. The
consequence is that the stack will grow longer and longer while A isn't
yet done with compaction, which will lead to a growing performance
impact.
Instead of aborting auto-compaction altogether, let's gracefully handle
this situation by instead compacting tables which aren't locked. To do
so, instead of locking from the beginning of the slice-to-be-compacted,
we start locking tables from the end of the slice. Once we hit the first
table that is locked already, we abort. If we succeeded to lock two or
more tables, then we simply reduce the slice of tables that we're about
to compact to those which we managed to lock.
This ensures that we can at least make some progress for compaction in
said scenario. It also helps in other scenarios, like for example when a
process died and left a stale lockfile behind. In such a case we can at
least ensure some compaction on a best-effort basis.

The git-fsck(1) only implicitly checks the reference, it does not fully
check refs with bad format name such as standalone "@".
However, a file ending with ".lock" should not be marked as having a bad
ref name. It is expected that concurrent writers may have such lock files.
We currently ignore this situation. But for bare ".lock" file, we will
report it as error.
In order to provide such checks, add a new fsck message id "badRefName"
with default ERROR type. Use existing "check_refname_format" to explicit
check the ref name. And add a new unit test to verify the functionality.

When calling `raw_object_store_clear()`, we close and free several
resources associated with the object store. Part of that is to close and
free all the packfiles, which is handled by `close_object_store()`.
That function really only ends up closing the packfiles though, but it
doesn't free them. And in fact it can't, as that function is being
called via `run_command()` when `close_object_store = 1`, which is done
e.g. when we execute git-maintenance(1). At that point, other structures
may still have references on those packfiles, and thus we cannot free
them here. So while it is in fact intentional that we really only close
them, the result is a memory leak because `raw_object_store_clear()`
does not free them, either.
Fix the leak by freeing the packfiles in `raw_object_store_clear()`.

When opening a submodule ref storage we accidentally use the ref storage
format of the owning repository, not of the submodule repository. As
submodules may have a different storage format than their parent repo
this can lead to bugs when trying to access the submodule ref storage
from the parent repository.
One such bug was reported when performing a recursive pull with mixed
ref stores, which fails with:
$ git pull --recursive
fatal: Unable to find current revision in submodule path 'path/to/sub'
The same issue occurs when adding a repository contained in the working
tree with a different ref storage format via `git submodule add`.
Fix the bug by using the submodule repository's ref storage format
instead and add some tests. Note that the test for `git submodule
status` was included as a precaution, only. The command worked alright
even without the bugfix.

When recursively cloning a repository with a non-default ref storage
format, e.g. by passing the `--ref-format=` option, then only the
top-level repository will end up using that ref storage format, and
all recursively cloned submodules will instead use the default format.
While mixed-format constellations are expected to work alright, the
outcome still is somewhat surprising as we have essentially ignored
the user's request.
Fix this by propagating the requested ref format to cloned submodules.

As submodules are proper self-contained repositories, it is perfectly
valid for them to have a different ref storage format than their parent
repository. There is no obvious way for users to ask for the ref storage
format when initializing submodules though. Whether the setup of such
mixed-ref-storage-format constellations is all that useful remains to be
seen. But there is no good reason to not expose such an option, and we
will require it in a subsequent patch.
Introduce a new `--ref-format=` option for git-submodule(1) that allows
the user to pick the ref storage format. This option will also be used
in a subsequent commit, where we start to propagate the same flag from
git-clone(1) to cloning submodules with the `--recursive` switch.

Many existing tests in this script perform operation(s) and then use
test_when_finished to define how to undo the effect of the
operation(s).
This is backwards. When your operation(s) fail before you manage to
successfully call test_when_finished (remember, that these commands
must be all &&-chained, so a failure of an earlier operation mean
your test_when_finished may not be executed at all). You must
establish how to clean up your mess with test_when_finished before
you create the mess to be cleaned up.
Also make sure that the body of test_when_finished deals with case
where the cruft it wants to remove failed to be created, by using
"rm -f" (instead of "rm") to remove potential cruft files, and
having "|| :" after "git notes remove" to remove potential cruft
notes---both of these by default fail when asked to remove something
that does not exist, instead of being silently idempotent no-ops.

Along with the migration, make 'add' tests from the shell script order
agnostic in unit tests, since they iterate over entries with the same
keys and we do not guarantee the order. This was already done for the
'iterate' tests[1].
The helper/test-hashmap.c is still not removed because it contains a
performance test meant to be run by the user directly (not used in
t/perf). And it makes sense for such a utility to be a helper.
