rust-status: only visit parts of the tree requested by the matcher

This is an optimization that the matcher is designed to support, but
we weren't doing it until now.  This is primarily relevant for
supporting "hg status [FILES]", where this optimization is crucial for
getting good performance (without this optimization, that command will
still scan the entire tree, and just filter it down after the fact).

When this optimization fires we have to return false from
traverse_fs_directory_and_dirstate, representing that that part of the
tree *might* have new files which we didn't see because we skipped
parts of it.  This only affects the cached result of the status, and
is necessary to make future status operations (which might use a
different matcher) work properly.
