* Connect() now sets the initial send queue sequence before calling _SendQueued() 

so that it's already correct at this point (even though it's currently not
  possible to queue data before connecting, it might be in some point in the future).
* ListenReceive() did not initialize the initial send queue sequence of the new
  endpoint correctly; it took the values from the wrong endpoint (itself).
* Suppressed the debug output "FIN ack'd" when the connection was not even established
  yet.
* Minor debug output improvements.
