Implement hostname->ip lookup function

* src/process.c (conv_sockaddr_to_lisp): Add include_port
argument.  Don't put a port in the result if this is false.
(conv_addrinfo_to_lisp, Fprocess_datagram_address)
(connect_network_socket, network_interface_list)
(network_interface_info, server_accept_connection)
(init_process_emacs): Update callers.
(Fnetwork_lookup_address_info): New function.  Performs hostname to
ip address lookups.

* src/w32.c (network_interface_get_info): Update callers of
  conv_sockaddr_to_lisp

* etc/NEWS : mention addition of 'network-lookup-address-info'
