Add support for multiple post-rewrite hooks, both for "git commit
--amend" and "git rebase". Unify the hook handling between the am-based
and sequencer-based code paths.
Additionally add support for multiple prepare-commit-msg hooks.
Note that the prepare-commit-msg hook is not passed a set of hooks
directly because these are discovered later when the code calls
run_hooks_le.
