data minimization on client requests

[Hal Murray]

I just pushed the code to implement 
    https://datatracker.ietf.org/doc/draft-ietf-ntp-data-minimization/

It only changes the contents of client request packets.  Currently, there is 
no option.  It happens all the time.  If anybody figures out a good reason to 
disable it, we can add that code.


Actually, it uses the old mode if you specify version 3 protocol.
