rebase: support multiple roots for rebaseset

We have all the necessary mechanism to rebase a set with multiple roots, we only
needed a proper handling of this case we preparing and concluding the rebase.
This changeset des that.

Rebase set with multiple root allows some awesome usage of rebase like:

- rebase all your draft on lastest upstream

  hg rebase --dest @ --rev 'draft()'

- exclusion of specific changeset during rebase

  hg rebase --rev '42:: - author(Babar)'

-  rebase a set of revision were multiple roots are later merged

  hg rebase --rev '(18+42)::'
