[PATCH] Add case insensitive support in matching pathspec

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Commit 21444f1 (Add case insensitivity support when using git ls-files
- 2010-10-03) teaches match_pathspec() to ignore case when
core.ignorecase=true.

match_pathspec_depth() is developed independently and does not have
this feature. Teach it.

 On top of nd/struct-pathspec, but requires jj/icase-directory. I can
 rebase the series on top of master if it causes too many conflicts.
