  Add limited support for Solaris 10 ZFS-style ACLs: just enough to
  handle file_has_acl.
  * lib/acl-internal.h, lib/acl_entries.c, lib/file-has-acl.c: New files.
  * lib/acl.c: Move header inclusions and related macro defns into
  lib/acl-internal.h.
  (S_ISLNK): Remove defn, since that's now done for us.
  (file_has_acl): Move to lib/file-has-acl.c.
  Call acl_trivial if available.  This is the crucial part of the fix.
  (acl_entries): Move to lib/acl_entries.c.  Now extern, since it's
  shared within the library.  Rewrite a bit, partly to make it compatible
  with the GNU coding style.
  * m4/acl.m4 (AC_FUNC_ACL): Add AC_LIBOBJ([file-has-acl]).
  Remove unnecessary double-quotes.
  Don't test for acl_to_text; the build will catch that.
  Replace acl_entries if it doesn't exist and it is needed.
  Check for -lsec and acl_trivial (as used on Solaris 10).
  * modules/acl (Files): Add lib/acl-internal.h, lib/acl_entries.c,
  lib/file-has-acl.c.
  (Depends-on): Add sys_stat, for S_ISLNK.
