commit: add --force-close-branch flag to close a non-head changeset While closing branch from a changeset which is not a branch head current implementation abort this action in every case but, there can be the situations where the changeset is not a local head but could be a remote head. This patch adds the functionality to bypass the "abort: can only close branch heads" by introducing --force-close-branch flag. Test case changes demonstrate the new functionality added.

rust-dirstate: call new "dirs" rust implementation from Python This is a simple module attribute replacement, will take precedence over the Python and C implementations. Differential Revision: https://phab.mercurial-scm.org/D6395

rust-dirstate: add "dirs" rust-cpython binding There is an obvious performance and memory issue with those bindings on larger repos as it copies and allocates everything at once, round-trip. Like in the previous patch series, this is only temporary and will only get better once we don't have large data structures going to and from Python.
