Merge branch 'kb/status-ignored-optim-2' 

Fixes a handful of issues in the code to traverse working tree to
find untracked and/or ignored files, cleans up and optimizes the
codepath in general.

* kb/status-ignored-optim-2:
  dir.c: git-status --ignored: don't scan the work tree twice
  dir.c: git-status --ignored: don't scan the work tree three times
  dir.c: git-status: avoid is_excluded checks for tracked files
  dir.c: replace is_path_excluded with now equivalent is_excluded API
  dir.c: unify is_excluded and is_path_excluded APIs
  dir.c: move prep_exclude
  dir.c: factor out parts of last_exclude_matching for later reuse
  dir.c: git-clean -d -X: don't delete tracked directories
  dir.c: make 'git-status --ignored' work within leading directories
  dir.c: git-status --ignored: don't list empty directories as ignored
  dir.c: git-ls-files --directories: don't hide empty directories
  dir.c: git-status --ignored: don't list empty ignored directories
  dir.c: git-status --ignored: don't list files in ignored directories
  dir.c: git-status --ignored: don't drop ignored directories

A bit-field of options (the `*IGNORED*` flags are mutually exclusive):
`DIR_SHOW_IGNORED`:::
The traversal is for finding just ignored files, not unignored
files.
Return just ignored files in `entries[]`, not untracked files.
`DIR_SHOW_IGNORED_TOO`:::
Similar to `DIR_SHOW_IGNORED`, but return ignored files in `ignored[]`
in addition to untracked files in `entries[]`.
`DIR_COLLECT_IGNORED`:::
Special mode for git-add. Return ignored files in `ignored[]` and
untracked files in `entries[]`. Only returns ignored files that match
pathspec exactly (no wildcards). Does not recurse into ignored
directories.
`DIR_SHOW_OTHER_DIRECTORIES`:::

Internal use; keeps track of allocation of `entries[]` array.
`ignored[]`::
An array of `struct dir_entry`, used for ignored paths with the
`DIR_SHOW_IGNORED_TOO` and `DIR_COLLECT_IGNORED` flags.
`ignored_nr`::
