revlog: add optional stoprev arg to revlog.ancestors()

This will be used as a step in removing reachable() in a future diff.
Doing it now because bryano is in the process of rewriting ancestors in
C.  This depends on bryano's patch to replace *revs with revs in the
declaration of revlog.ancestors.
