rust-status: collect traversed directories if required
Some commands (`hg purge` notably) register the `traversedir` callback on their
matcher to run said callback every time a directory is traversed.
This is the first of three patches, further broadening Rust support for status.
Unfortunately, there is no way around collecting a full `Vec` (or any other
owned datastructure, like a radix tree) and pushing it back up the Python layer
since keeping the Python callback in a closure would mean giving up
multithreading because of the GIL, which is obviously unacceptable.
Performance is still a lot better than the Python+C path.
Running `hg clean/purge` on Netbeans' repo (100k files):

==================================== Testing head checking code: Case C-4 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category C: case were the branch is only partially obsoleted TestCase 4: 2 changeset branch, only the base is pruned .. old-state: .. .. * 2 changeset branch .. .. new-state: .. .. * old base is pruned .. * 1 new unrelated branch .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
