QPID-3401 Stubbing out Destination, Topic and Queue implementations.

The Destination objects would be immutable.
The base class QpidDestination which implements javax.jms.Destination is
an abstract class.
QpidTopic and QpidQueue which implements the respective Topic and
Queue interfaces provides a concrete implementation.
