it's used to register a callback for a tap listener invoked if the specified command line argument is specified to the "-z" flag. Move it, along with routines to: look up a "-z" argument in the table constructed by "register_tap_listener_cmd_arg()" and either save the full argument to "-z" and the corresponding listener if it's found or return a failure indication if it isn't; list the available tap listeners; call the "init" routines for the tap listeners saved in the table above; and have Ethereal and Tethereal use those routines. svn path=/trunk/; revision=13993
