[PATCH 0/3] posix: glob fixes and refactor (1st part)

[Adhemerval Zanella]

This is a subset from my previous patch for glob refactor [1] with the
fixes that do not intend to change glob internal semantics or fix any
issue.  They are focus instead on sync with gnulib (with some code
exceptions) and consolidate the implementation to simplify it.

>From previous comments I also added a de-couple one for remove non
unix code from glob.c implementation (since the idea is to gnulib
to add simpler wrappers if required).
