Merge branch 'nd/rewritten-ref-is-per-worktree'

"git rebase" uses the refs/rewritten/ hierarchy to store its
intermediate states, which inherently makes the hierarchy per
worktree, but it didn't quite work well.

* nd/rewritten-ref-is-per-worktree:
  Make sure refs/rewritten/ is per-worktree
  files-backend.c: reduce duplication in add_per_worktree_entries_to_dir()
  files-backend.c: factor out per-worktree code in loose_fill_ref_dir()
