phases: add set per phase in C phase computation

To speed up the computation of draft(), secret(), divergent(), obsolete() and
unstable() we need to have a fast way of getting the list of revisions that
are in draft(), secret() or the union of both: not public().

This patch extends the work on phase computation in C and make the phase
computation code also return a list of set for each non public phase.
Using these sets we can quickly obtain all the revisions of a given phase.
We do not return a set for the public phase as we expect it to be roughly the
size of the repo. Also, it can be computed easily by substracting the entries in the
non public phases from all the revs in the repo.
