NTP: Detect out-of-order packets

Browse source 
The NTP mode provides us with the identity of the endpoints. For the
simple CLIENT / SERVER modes, flip the connection if we detect
orig/resp disagreeing with what the message says. This mainly
results in the history getting a ^ and the ntp.log / conn.log
showing the corrected endpoints.

Closes #2998.
