[StGIT PATCH 3/7] Revert part of the reverted commit that we want to keep.

[Yann Dirson <ydirson@altern.org>]

- get rid of unused real_rebase parameter
- revive git.all_refs()

This commit can freely be used to demonstrate the usefulness of
_always_ separating different issues in different patches :)
