> The attached fix resolves a problem in KahaDBStore.KahaDBSession in which addMessage()
wasn't using the caller supplied message key but instead allocated a new key. Without using
the user supplied key, subsequent deletes would not properly delete the message. Also fixed
corresponding test cases to provide a message key when adding messages. 
> Also made some fixes to synchronization and delayed event processing in BrokerDatabase.
The resulting code is not as performant in swimlanes testing, and should be optimized in the
future (the problem is too many threads synchronizing on the opQueue is causing a lot of contention).

> Finally added some miscellaneous fixes to OpenwireProtocolHandler and the test drivers
to avoid/detect duplicate messageIds.
