[PATCH 00/10] nd/wildmatch take 2

The first four patches are ignore/attr cleanups. The following imports wildmatch, nothing new there. The last patch limits allowed syntax to a safe subset: "abc/**", "**/def" and "abc/**/def".

Nguyễn Thái Ngọc Duy (10):
  gitignore: make pattern parsing code a separate function
  attr: avoid strlen() on every match
  attr: avoid searching for basename on every match
  attr: more matching optimizations from .gitignore
  Import wildmatch from rsync
  wildmatch: remove static variable force_lower_case
  wildmatch: fix case-insensitive matching
  Integrate wildmatch to git
  Support "**" in .gitignore and .gitattributes patterns using
    wildmatch()
  gitignore: forbid "abc**def"
