--list-protocol was printing a *:// entry, which looked strange at best. The "*" protocol was used to always match everything, so stream_cb.c could hook in custom protocols with a prefix chosen by the API user. Change it instead so that an empty protocol list means "match all", which also gets rid of the special-cased "*" entry.
