rebase: properly handle --collapse when creating obsolescence marker In collapse mode, that content of state is not suitable to compute obsolescence markers. We explicitly pass the resulting revision instead and use it as the successors for all elements of the rebased set.

rebase: allow creation obsolescence relation instead of stripping When obsolescence feature is enabled we now create markers from the rebased set to the resulting set instead of stripping. The "state" mapping built by rebase holds all necessary data. Changesets "deleted" by the rebase are marked "succeeded" by the changeset they would be rebased one. That the best guess of "successors" we have. Getting a successors as meaningful as possible is important for automatic resolution of obsolescence troubles. In other word, emptied changeset will looks collapsed with their former parents. (see "empty changeset" section of the test if you are still confused)

rebase: extract final changesets cleanup logic in a dedicated function At the end of the rebase, rebased changesets are currently stripped. This behavior will be eventually dropped in favor of obsolescence marker creation. The main rebase function is already big and branchy enough. This changeset move the clean-up logic in a dedicated function before we make it more complex.
