rust: Add Repo::dirstate_map and use it in `rhg status` This moves low-level dirstate wrangling out of the status command and into a more reusable location. The open dirstate map is lazily initialized and kept on the Repo object, for reuse by sub-sequent calls. Differential Revision: https://phab.mercurial-scm.org/D11398
