Title: =rem #3606 Properly reset system message buffer between remote sys restarts

Problem arised when:
- remote system shuts down, but SHUTDOWN message is lost
- then remote system comes back with same address
causing out of synch resend buffers

Solution: defer transfer of system messages and processing of queued acknowledgements until remote UID is confirmed to be same or different.

Needs backport to 2.2
