In the upcoming git-rebase-to-C rewrite, it is a common operation to
check if the worktree has unstaged changes, so that it can complain that
the worktree is dirty.
builtin/pull.c already implements this function. Move it to
rebase-common.c so that it can be shared between all rebase backends and
git-pull.
