* src/qpid/framing/ChannelAdapter.cpp: Use handler chains

	for in and outbound frames.

	* src/qpid/framing/InputHandler.h, OutputHandler.h, FrameHandler.h:
	All handlers pass AMQFrame& and have consistent memory management.
	Terminal OutputHandlers used to take ownership and delete frame, now
	they make a shallow copy instead.

	* src/qpid/framing/Handler.h, FrameHandler.h: Simplified.

	* src/qpid/client/ClientConnection.cpp: 
	* src/qpid/broker/Connection.cpp: 
	* src/qpid/broker/BrokerChannel.cpp:
	   Update for ChannelAdapter changes.
