dirstate: force _checkexec to return a bool posix.checkexec can return True, False, or None. The rust status implementation expects a boolean, so make sure _checkexec returns a boolean. Differential Revision: https://phab.mercurial-scm.org/D8432

locking: wait for locks in `hg cp` and `hg mv` I traced this back to revision 1822 (64df422), and there's no explanation why we would prefer to error out instead of waiting for the locks. Differential Revision: https://phab.mercurial-scm.org/D8464

nodemap: teach `hg debugformat` about the persistent nodemap option We have a new requirement, we should display it. Differential Revision: https://phab.mercurial-scm.org/D8430

upgrade: support the --quiet flag The command is currently very verbose with a various bit of output being time sensitive or randomized. The make invocation bulky and hard to match in the test. We move various message from `ui.write` to `ui.status` in order for the `--quiet` flag to have effect and helps the situation. As a side benefit, we can replace the various redirection to > /dev/null with the --quiet flag. Differential Revision: https://phab.mercurial-scm.org/D8429

upgrade: clearly list optimisations This makes the command operation clearer. And this will be necessary to have a short version of this information with the next changesets, teaching `hg debugupgraderepo` about `--quiet`. Differential Revision: https://phab.mercurial-scm.org/D8428

nodemap: move the mode option to storage.revlog.nodemap.mode The option stay experimental as long as the main feature is. Differential Revision: https://phab.mercurial-scm.org/D8422

nodemap: move the option for mmap usage to storage.revlog.nodemap.mmap The option is stay experimental as long as the main feature is. Differential Revision: https://phab.mercurial-scm.org/D8421
