QPID-6727: [Java Broker] change default network buffer size to 256kB and move 
QpidByteBuffer pool creation to BrokerAdapter

> Remove sendBufferSize/receiveBufferSize from AmqpPort and make max 
> framesize/sendBufferSize/receiveBufferSize share a single source

>
> 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
