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)

Make sure import still works with branch information in patches.
