evolve: extend obsstore object to use prune parent information
Now that we have the information, we can use it to build a mapping to access all
marker that prune a children of a node. This is similar to what we do for
successors and precursors.
The performance impact is a few tens of second on my mercurial clone.
Experimenting is worth the trouble.
