[PATCH 0/9] posix: glob fixes and refactor

[Adhemerval Zanella <adhemerval dot zanella at linaro dot org>]

This patchset sync GLIBC glob with latest gnulib code (064df0b).
Instead of dump a large patchset, I decided to split it since
different commits fixes different GLIBC bugs:

  * Patch 1/9 sync with gnulib code b5ec983 and fixes a GLIBC
    specific code regarding DT_UNKNOWN, DT_DIR, and DT_LNK
    definition.  Paul I think we should sync it back to gnulib.

  * Patch 2/9 sync with gnulib 2adc376c55194 and fixes BZ #19971.

  * Patch 3/9 sync with gnulib fd1daf4 and also fixes BZ #866.

  * Patch 4/9 sync with gnulib 3866ef6.  It is related to
    scratch_buffer code.

  * Patch 5/9 sync with gnulib 5db9301.

  * Patch 6/9 sync with gnulib 064df0b and thus it fixes
    BZ #1062.

  * Patch 7/9 is a glob consolidation to avoid the multiple
    architecture implementations.

  * Patch 8/9 just refactor internal code to use an enumeration
    instead of numeric constants.

  * Patch 9/9 fixes BZ #10246.

I think patches from 1 to 8 should be safe to push.
