  openat: allow return of fd 0
  
  Partially reverts patch fc33350 from 2009-09-02.
  
  * modules/chdir-long (Depends-on): Relax openat-safer to openat.
  * modules/save-cwd (Depends-on): Replace fcntl-safer with
  unistd-safer.
  * lib/chdir-long.c (includes): Replace "fcntl--.h" with
  <fcntl.h>; this module does not leak fds.
  * lib/openat.c (includes): Do not use "fcntl_safer"; plain openat
  must be allowed to return 0, leaving openat_safer to add the
  safety.
  (openat_permissive): Avoid writing to just-opened fd 2 if
  restoring the current directory fails.
  * lib/openat-die.c (openat_restore_fail): Add comment.
  * lib/save-cwd.c (includes): Make "fcntl--.h" conditional.
  (save_cwd): Guarantee safe fd, but without use of open_safer.
  * tests/test-openat.c: New test.
  * modules/openat-tests (Files, Makefile.am): Distribute and build
  new file.
