ancestor: caching the parent list to improve performance...

ancestor: caching the parent list to improve performance When computing the DAG depth, we walk through all ancestors: this commit adds memoization during that first step. Then, the memorized parents are fetched from a dict instead of calling parents() on each vertex. This tweak, according to Kcachegrind, improves ancestor() performance by 16% when cloning a big repository.
