* Added missing AT_EACCESS.

Browse Source 
* Implemented renameat(), faccessat(), fchownat(), fchmodat(), and mkfifoat().
* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
  effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
  (more or less). This also closes ticket #4928.
