  Modified files:
    sys/kern             kern_ntptime.c 
  Log:
  Create a separate pps_offset variable to use for applying the
  hardpps() produced offset component.  This is tested and behaved
  stable with frequency offsets from -338.05 to +499.91 PPM.
  
  Interestingly the machine I tested this on would fail if the clock
  were slower than 14.3132 MHz whereas it was perfectly happy to run
  at 16.384 MHz, in other words [-340PPM ... +14.4%]
  
  Make pps_shift tweakable with sysctl.
