revert: add support for reverting subrepos without --no-backup and/or --all

When a subrepo is reverted but --no-backup is not set, call revert on the
subrepo that is being reverted prior to updating it to the revision specified
in the parent repo's .hgsubstate file.

The --all flag is passed down to the subrepo when it is being reverted. If the
--all flag is not set, all files that are modified on the subrepo will be
reverted.
