Subject: [PATCH] LP#1684202: Protect against missing features; Make feature
 more general

I've wrapped the BroadcastChannel code in a test derived from the auth version
of the same concept.  Also broadcasting the full set of record IDs and the
pre-update call number IDs for other interfaces that might be interested. The
channel name is also made more generic and made to follow the precedent from
the auth channel name.
