    For ISDN, don't create an endpoint by ID and then use it.
    
    That isn't working, because it depends on the notion that for every
    "endpoint type" there's a "port type" for the packet_info structure;
    that's not true for ISDN channels.
    
    The whole point of "use the packet_info structure when trying to find a
    conversation and create it if it doesn't exist" is to use address
    information *already filled in by somebody for use by other dissectors*;
    we don't do that with the ISDN channel number, because there's no *need*
    to do so.
    
    So just add a new find_or_create_conversation_by_id() routine, which
    passes the packet_info structure to get the frame number, and explicitly
    passes the endpoint type and ID.  Use that in the ISDN dissector.
