Merge branch 'nd/no-more-fnmatch'

We started using wildmatch() in place of fnmatch(3); complete the
process and stop using fnmatch(3).

* nd/no-more-fnmatch:
  actually remove compat fnmatch source code
  stop using fnmatch (either native or compat)
  Revert "test-wildmatch: add "perf" command to compare wildmatch and fnmatch"
  use wildmatch() directly without fnmatch() wrapper
