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.
