  openat: detect Solaris fchownat bug
  
  Solaris 9 fchownat(dir,"name/",uid,gid,flag) has same bugs as
  chown and lchown.
  
  * lib/fchownat.c (rpl_fchownat): Work around Solaris bug.  Avoid
  penalizing glibc chownat when only lchownat is broken.
  * m4/openat.m4 (gl_FUNC_FCHOWNAT): Replace fchownat if there are
  trailing slash bugs.
  * doc/posix-functions/fchownat.texi (fchownat): Document the bug.
  * modules/openat-tests (Files): Include more files.
  (Depends-on): Add mgetgroups, sleep, stat-time.
  (configure.ac): Add additional checks.
  (Makefile.am): Build new test.
  * tests/test-fchownat.c: New file.
