inhibit: fix compat with rebaseskipobsolete
We wrap _computeobsoletenotrebased and _clearrebased to fix the following case:
- Assuming that we have markers from revisions of the rebase set and
destination set and that these markers are inhibited
- At the end of the rebase the nodes are still visible because rebase operate
without inhibition and skip these nodes
Had we not have those markers to begin with the revisions could be hidden at
the end of the rebase.
We keep track in repo._obsoletenotrebased of the obsolete commits skipped by
the rebase and lift the inhibition at the end of the rebase.
We add three test cases to make sure that the edge cases are covered.
