Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

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()`.

Same as with "clone", users may want to add a submodule to a repository
with a non-default ref storage format. Wire up a new `--ref-format=`
option that works the same as for `git submodule clone`.

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.
