[WIP v1 0/4] mv: fix out-of-cone file/directory move logic

Before integrating 'mv' with sparse-index, I still find some possibly buggy UX when 'mv' is interacting with 'sparse-checkout'.

So I kept sparse-index off in order to sort things out without a sparse index. We can proceed to integrate with sparse-index once these changes are solid.

Note that this patch is tentative, and still have known glitches, but it illustrates a general approach that I intended to harmonize 'mv' with 'sparse-checkout'.

Shaoxuan Yuan (4):
  mv: check if out-of-cone file exists in index with SKIP_WORKTREE bit
  mv: add check_dir_in_index() and solve general dir check issue
  mv: add advise_to_reapply hint for moving file into cone
  t7002: add tests for moving out-of-cone file/directory
