[PATCH 4/7] builtin rebase: support --quit

[Pratik Karki]

With this patch, the builtin rebase handles the `--quit` action which
can be used to abort a rebase without rolling back any changes performed
during the rebase (this is useful when a user forgot that they were in
the middle of a rebase and continued working normally).
