[PATCH 3/8] Integrate wildmatch to git

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

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=UTF-8, Size: 13321 bytes --]

This makes wildmatch.c part of libgit.a and builds test-wildmatch; the
dependency on libpopt in the original has been replaced with the use
of our parse-options. Global variables in test-wildmatch are marked
static to avoid sparse warnings.
