Change the InactivityMonitor to clear its flag as soon as a few bytes are received on a connection rather than only after an entire message has been assembled.

      Description

      On slow connections with larger messages to be exchanged, the inactivity monitor might kick in, drop the network connection and re-establish it again. This prevents two brokers from exchanging larger messages on a slow connection as the transmission always gets interrupted.
      See the discussion of this on http://activemq.apache.org/slow-networks-drop-large-messages.html.
      The problem is that the InactivityMonitor always waits for a complete message to be assembled on an active connection before clearing its internal flag.

      I propose to change the behavior of the InactivityMonitor so that it clears its flag already when a few bytes were received on a network connection rather than waiting for the entire message to be sent. This should work around the problem of connections being dropped and re-established periodically when receiving large messages.
