keep a "trustlevel" per peer. loose credit for loosing a packet, loose
a lot of credit for not having supplied us with enough data within an
adjtime run interval, and get a little credit each time we get a good
reply packet. if a peer is below 20%, only send a packet occasionally to
see wether it is back. send out queries much more often between 20 and 80%
to (re-)sync quickly, and above 80% usethe regular interval.
do not use peers < 60% for calculating teh local clock offset.
