/* Notify message to the client. The notify arguments are sent in the

   from the server except for ID's.  If ID is received application receives
   the corresponding entry to the ID. For example, if Client ID is received
   application receives SilcClientEntry.  Also, if the notify type is
   for channel the channel entry is sent to application (even if server
   does not send it because client library gets the channel entry from
   the Channel ID in the packet's header). */
