tree:<depth> should not traverse overly-deep trees
If we are traversing a tree which is too deep, then there is no need to
traverse the children. Skipping children is much faster than traversing
the possibly thousands of objects which are directly or indirectly
referenced by the tree.

Preliminary support for tree:<depth> filter
This is used when fetching, and in particular to populate a partial
clone or a virtual file system cache as the user navigates. With this,
a client can pre-fetch a few directories deeper than only the current
directory.
depth:0 will omit all trees, and is useful if you only want to fetch
the commits of a repository, or fetch just a single tree or blob object.
depth:1 will fetch only the root tree of all commits fetched. depth:2
will fetch the root tree and all blobs and tree objects directly
referenced from it. depth:3 gets one more level, and so on. depth:#
will not filter a blob or tree that is explicitly marked wanted.
Bitmaps are disabled when this filter is used.
This implementation is quite slow because it iterates over all omitted
objects rather than skipping them. This will be addressed in follow-up
commits.

Revert "Use try-with-resources in SubmoduleWalk"
This reverts commit 39b0b51b1253f569888db3578b01708a14360b69. Before
that change, SubmoduleWalk.forPath transferred ownership to the caller
on success. Afterward, it returns a closed SubmoduleWalk to the caller,
which does not appear to be intentional.
DepthGenerator marks commits reinteresting for the ones that are
reachable from unshallow commits as it walks over the revisions. Those
unshallow commits won't necessarily be processed first. Because of this,
even if a commit is reachable from unshallow commits, if it's processed
before the uninteresting commits, it will not be processed as
reinteresting and processed as uninteresting. This causes unshallow
git-fetch to be failed.
This changes DepthGenerator to process unshallow commits first
independent to their depth. This makes uninteresting flag carry work
properly.
