(Fformat_network_address): New function.

Browse source 
(syms_of_process): Defsubr it.
(list_processes_1): Use it to format :local/:remote address if
service/host is not set; before emacs would crash in that case.
(Fmake_network_process): Don't use Ffind_operation_coding_system
to setup coding system if host or service is not set.
