Lei Zhang 755f97f534 Add a callback mechanism for communicating messages to callers.
Every time an event happens in the library that the user should be
aware of, the callback will be invoked.

The existing diagnostic mechanism is hijacked internally by a
callback that creates an diagnostic object each time an event
happens.
