Subject: 	* Summary: generalized Invoker visitor to all *Operations and 
   *Handler classes, client and broker. Single template 	  free
 function invoke(Invocable, const AMQBody&); works for 	  all invocable
 handlers.

	* rubygen/templates/OperationsInvoker.rb: Generates invoker
	  visitors for all Operations classes, client and server.

	* src/qpid/framing/Invoker.h: Invoker base class and
	  template invoke() function.

	* rubygen/templates/structs.rb: add generic invoke method template
	  to invoke an arbitrary object with the correct memeber function.

	* src/qpid/framing/AMQMethodBody.cpp, .h: Removed invoke(),
	  replaced by qpid::framing::invoke()

	* src/qpid/broker/SemanticHandler.cpp, ConnectionHandler.cpp:
	  Replace AMQMethodBody::invoke with invoke() free function.

	* src/qpid/framing/StructHelper.h: Avoid un-necessary alloc
	  and copy in encode/decode.
