Fix some Darwin-7.9.0 porting problems reported by Bruno Haible in
<http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00063.html>.
* dirchownmod.c: Include lchown.h.
* lchown.c: Don't include files that lchown.h now includes.
Don't declare chown, since lchown.h now does that.
* lchown.h: Include errno.h, sys/types.h, unistd.h.
(lchown): Define to rpl_chown if lchown is declared but
does not exist.  Declare using a prototype if lchown is not
declared.  Add a copyright notice.
* mkstemp.h: Include <unistd.h>.
* openat.c: Include lchown.h.
[m4/ChangeLog]
* lchown.m4 (gl_FUNC_LCHOWN): Check whether lchown is declared.

        * fcntl_.h (O_NOFOLLOW): Don't depend on O_NOFOLLOW_IS_INEFFECTIVE;
        we now test for that separately.
        * fts.c (fts_safe_changedir): Inspect HAVE_WORKING_O_NOFOLLOW
