Merge branch 'dt/refs-bisection'

Move the refs used during a "git bisect" session to per-worktree
hierarchy refs/worktree/* so that independent bisect sessions can
be done in different worktrees.

* dt/refs-bisection:
  refs: make refs/bisect/* per-worktree
  path: optimize common dir checking
  refs: clean up common_list
