[PATCH 0/5] Sparse checkout fixes

[on top of nd/maint-fix-add-typo-detection]

This fixes a sparse pattern sometimes won't match a directory if
 - it does not end with a slash
 - it has wildcards

The series also improves performance a bit, thanks to 3/5, skip-worktree bits are precomputed.

Improvements in the previous round [1] are left out. I will need to polish them a bit more.

Nguyễn Thái Ngọc Duy (5):
  cache.h: remove surrounding brackes and realign CE_* constants
  dir.c: add free_excludes()
  unpack-trees: move all skip-worktree checks back to unpack_trees()
  unpack-trees: fix sparse checkout's "unable to match directories"
  Revert "excluded_1(): support exclude files in index"
