  openat: fix openat bugs on Solaris 9
  
  openat(fd,"file/",O_RDONLY) mistakenly succeeded.
  
  * lib/openat.c (rpl_openat): Work around Solaris 9 bug.
  * m4/openat.m4 (gl_FUNC_OPENAT): Also replace openat on Solaris.
  * modules/openat (Depends-on): Add open.
  * m4/fcntl_h.m4 (gl_FCNTL_H_DEFAULTS): Provide new default.
  * modules/fcntl-h (Makefile.am): Substitute it.
  * lib/fcntl.in.h (openat): Declare replacement.
  * doc/posix-functions/openat.texi (openat): Document this.
