revset: remove grandparent by using reachableroots
This patch is part of a series of patches to speed up the computation of
revset.reachableroots by introducing a C implementation. The main motivation
is to speed up smartlog on big repositories. At the end of the series, on our
big repositories the computation of reachableroots is 10-50x faster and
smartlog on is 2x-5x faster.
Before this patch, we had a custom computation for grandparent that was very
close to the idea of reacheablerooots. This patch expresses grandparent with
reachableroots to reduce the amount of code.
