> Currently the TCP/IP buffer sizes (sendBufferSize/receiveBufferSize) are attributes of
AmpqPort.  For the new memory model, supporting different ports using different receive buffers
would be problematic and cause inefficient use of direct memory.  Similarly clients using
framesizes where the framesize !=buffer size will be inefficient.
> # Remove sendBufferSize/receiveBufferSize from the Port.
> # Make max frame size and sendBufferSize/receiveBufferSize share a single source which
should be a context variable belonging to the Broker. Minimum size must be no smaller than
SSL netbuffer size
> # The context variable should be evaluated only once at Broker startup.
> # Upgraders should remove the attribute from AmqpPorts
