Denys Vlasenko d3fe960271 ntpd: be less eager to use shorter poll intervals 
* on step, poll interval drops to 8.5 mins instead of 32 seconds
* on total loss of all replies (no replies from any peer
  for last 8 requests), also drop poll interval to 8.5 mins
  instead of 32 seconds
* on send abd recv errors, RETRY_INTERVAL is now 32 seconds,
  not 5 seconds
* on timing out listening to reply, instead of unconditional
  shortening poll interval by x4, clamp it to NOREPLY_INTERVAL
  (512 seconds)
* if a largish offset is seen, clamp nexp poll interval
  to 128 seconds, not 64 seconds
