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.
