* Added fdopendir() (POSIX).

Browse Source 
* Got rid of <dirent_private.h> -- the __DIR structure is private to dirent.c,
  now. The attribute directory, index directory, and query functions use the
  the public POSIX API, so does the kernel module code. Those components were
  not initializing the structure correctly anymore since the introduction of
  telldir()/seekdir().
