Expose the wire format protocol to the ActiveMQConnection and TransportConnection objects
so that they know when then can use more advanced protocol options. This will be needed to implement producer flow control acking. git-svn-id: https://svn.apache.org/repos/asf/activemq/trunk@515863 13f79535-47bb-0310-9956-ffa450edef68
