- Usrv: Understand up_terminate and sending back down_terminate
triggering on_close_connection()
- Uclnt: bugfix: did not correctly deal with empty messages
- Uclnt: big rewrite (again), Use five threads beside the main thread:

- YInDispatcher: reading inbound messages from the network and passing them
on either to YCbQueue or to YMsgWindowQueue
- YOutQueue: queuing outbound messages
- YCbQueue: queing messages for all callbacks except onError()
- YMsgWindowQueue: queing messages for onError()
