builtin rebase: prepare for builtin rebase -i
The builtin rebase and the builtin interactive rebase have been
developed independently, on purpose: Google Summer of Code rules
specifically state that students have to work on independent projects,
they cannot collaborate on the same project.
One fallout is that the rebase-in-c and rebase-i-in-c patches cause no
merge conflicts but a royal number of tests in the test suite to fail.
It is easy to explain why: rebase-in-c was developed under the
assumption that all rebase backends are implemented in Unix shell script
and can be sourced via `. git-rebase--<backend>`, which is no longer
true with rebase-i-in-c, where git-rebase--interactive is a hard-linked
builtin.
This patch fixes that.
Please note that we also skip the finish_rebase() call for interactive
rebases because the built-in interactive rebase already takes care of
that. This is needed to support the upcoming `break` command that wants
to interrupt the rebase with exit code 0 (and naturally wants to keep
the state directory intact when doing so).
While at it, remove the `case` arm for the interactive rebase that is
now skipped in favor of the short-cut to the built-in rebase.
