phabricator: respect metadata sent by arc
Previously we only respect hg:meta sent by phabsend. This patch makes it
respect local:commits sent by arc as well. This avoids issues where phabread
could lose the author information.
Test Plan:
Commit using a customized user, send the patch using arc to a test
Phabricator instance, and then read the patch using phabread. Make sure it
preserves the user information.

dirstate: update backup functions to take full backup filename
Update the dirstate functions so that the caller supplies the full backup
filename rather than just a prefix and suffix.
The localrepo code was already hard-coding the fact that the backup name must
be (exactly prefix + "dirstate" + suffix): it relied on this in _journalfiles()
and undofiles(). Making the caller responsible for specifying the full backup
name removes the need for the localrepo code to assume that dirstate._filename
is always "dirstate".
