Fix a bug in the authz parser where using a group with no members in
an access entry was treated as an error instead of being ignored.

* subversion/libsvn_repos/authz_parse.c
  (add_to_group): Allow NULL user, to create empty groups. Update docstring.
  (expand_group_callback): Handle the case where a group has no users.
  (array_insert_ace): Ignore ACEs for empty groups.

* subversion/tests/cmdline/svnauthz_tests.py
  (svnauthz_empty_group_test): Remove XFail decorator.
   Extend the testcase to test recursive empty group expansion.

Fixes issue #4802
