Add metadata and state to track the RepositoryAsyncEventListener.processEvents(:List<AsyncEvent>) method invocations.

Browse Source 
Specifically, the listener state will track:

* The number of processEvents(:List<AsyncEvent>) method invocations.
* Whether the processEvents(..) method has ever been invoked.
* And, whether the processEvents(..) method has been invoked since the last check.

Introduces a protected doProcessEvents(:List<AsyncEvent>) method and changes processEvents(:List<AsyncEvent>) method to final.
