shrink-revlog: add "reverse postorder" and "postorder reverse" toposorts.

Based on a patch by Benoit Boissinot, adapted to the pluggable sort
algorithm design.  toposort_reversepostorder() is a very good
performer; it's designed to recreate what the revlog would have looked
like if Mercurial had parent deltas now.  toposort_postorderreverse()
is unstable and very inconsistent, but perhaps with some work it could
be made better.
