dirstate: move rust fast-path calling code to its own method This logic is about to get bigger, this will make it easier to read and not pollute the main Python logic. Differential Revision: https://phab.mercurial-scm.org/D7862

lfs: add "bytes" as the unit to the upload/download progress bar Facebook also passes `util.bytecount()` as a pretty formatter here, but our progress bar doesn't support that. Differential Revision: https://phab.mercurial-scm.org/D7872

phabricator: post revisions in ascending topological order (issue6241) The parent in phabricator ends up being the last revision posted, so sorting the user input into ascending order should be enough to preserve the proper relationships. Differential Revision: https://phab.mercurial-scm.org/D7874

doc: fix references to `revset.abstractsmartset` Differential Revision: https://phab.mercurial-scm.org/D7873

fsmonitor: properly handle str ex.msg ex.msg is always a str, since pywatchman uses str for exception messages.
