                                                  SignalMatch object.
  (AvahiService.remove): Really remove the group and the signal
                         connection, if any.
  (AvahiService.add): Always create a new group and signal connection.
  (AvahiService.cleanup): Changed to simply call remove().
  (AvahiService.server_state_changed): Handle and log more bad states.
  (AvahiService.activate): Set "follow_name_owner_changes=True" on the
                           Avahi Server proxy object.
  (ClientDBus.checked_ok): Do not return anything.
  (ClientDBus.CheckedOK): Do not return anything, as documented.
