listener configuration cleanup:

- have all listener creation functions take listen_opts as param,
  and call config_listener() when done, which adds the listener(s)
  to the current config list of listeners.
- make the fallback chain between interface(), host_v4() host_v6()
  and host_dns() obvious when creating an if_listener.
- fix a bug where the specified family was ignored if the listener
  is given as a hostname.
