(vc-workfile-unchanged-p): Add optional argument
specifying whether we want to compute the differences if the file is changed. Otherwise, use cmp instead of diff. (vc-next-action-on-file): Use new vc-workfile-unchanged-p option; this avoids recomputing the differences in some cases. (vc-backend-diff): OLDVERS is now optional; all callers changed. New optional argument CMP says to use `cmp' rather than `diff'.
