Subject: 	* src/qpid/cluster/SessionFrame.cpp, .h:  Wrap AMQFrame with 
   session UUID and direction.

	* src/qpid/cluster/Cluster.cpp, .h: Use SessionFrame.

	* src/qpid/framing/AMQFrame.h, .cpp: Added setBody(), inline getBody()

	* src/qpid/framing/Uuid.h, .cpp:  Clean up constructors, inline.

	* src/qpid/framing/Buffer.h: Put/get byte*, size_T.

	* src/qpid/cluster/SessionManager.cpp, .h:
	 - Maintain the session map.
	 - Handle frames from cluster, dispatch to proper channels.
	 - Implement HandlerUpdater for new channels and maintains
