* Removed the O_* modes that we currently don't and probably won't support

Browse Source 
(O_MOUNT, O_EXLOCK, and O_SHLOCK). I only left the non-standard O_TEMPORARY
  for the time being (as it shouldn't fool anyone).
* Fixed libutil that already used O_EXLOCK, even though it did not do anything.
* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.
* Added O_DIRECTORY.
