obsolete: compute unstable changeset
An unstable changeset is a changeset *not* obsolete but with some obsolete
ancestors.
The current logic to decide if a changeset is unstable is naive and very
inefficient. A better solution is to compute the set of unstable changeset with
a simple revset and to cache the result. But this require cache invalidation
logic. Simpler version goes first.
