The master reconnection in the binlogrouter used the housekeeper
recursively. This is no longer supported and the delayed worker call
mechanism should be used in its stead.
This clarifies what parts of the router are specific to the binlogrouter
and what are common between the binlogrouter and avrorouter.
Ideally, the two modules would use the same infrastructure to handle the
processing of replication events. This is the first, albeit small, step
towards making the code in the binlogrouter the common infrastructure.
