  faccessat: port to macOS (Bug#29231)
  
  macOS faccessat has the same bug that lstat does: if the file
  name ends in '/' it ignores the trailing slash.
  Problem reported for Emacs by Vincent Zhang.
  * doc/posix-functions/faccessat.texi (faccessat): Document this.
  * lib/faccessat.c (_GL_INCLUDING_UNISTD_H): Define and undef
  around the initial includes.  Include errno.h, string.h, sys/stat.h.
  (orig_faccessat) [HAVE_FACCESSAT]: New function.
  Include "unistd.h" after defining it.
  (rpl_faccessat) [HAVE_FACCESSAT]: New implementation.
  * lib/unistd.in.h (faccessat) [REPLACE_FACCESSAT]:
  Handle in the usual way.
  * m4/faccessat.m4 (gl_FUNC_FACCESSAT): Replace faccessat if
  lstat dereferences symlinks, since faccessat is likely to
  have the same problem.
  * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Default REPLACE_ACCESSAT.
  * modules/faccessat (Depends-on): Add fstatat.
  Depend if REPLACE_FACCESSAT is 1, too.
  (configure.ac): Link if REPLACE_FACCESSAT is 1.
  * modules/faccessat-tests (Depends-on): Add symlink.
  * modules/unistd (unistd.h): Substitute REPLACE_FACCESSAT.
  * tests/test-faccessat.c (main): Test for the bug.
