Add new topic command ETB, allowing services to set topic+setter+ts always

(provided channelTS != 0).

ETB is controlled by the EOPMOD capab. Fairly complicated
stuff is needed for older servers.

ETB can come from clients or servers, but at this time it
should only be sent from clients, as otherwise it is not
always possible to update older servers.
