resulted in vastly optimistic offset values reported to userland
(typically a factor 40+ too small). Apart from that, the code had
two sign-bugs.
Apply the hardpps() phase with the right sign with a simply
scaling by integration interval. (This may be too stiff at
long integration intervals, see below).
Allow pps_shiftmax to be reduced again.
Before this, the phase lock in hardpps() were broken, but due to
two bugs mostly cancelling out, it would end up basically working
with a large stochastic component. Now it behaves as one would
expect: smooth and quiet.
It seems that pps_shiftmax above 7..9 somewhere makes the phaselock
too weak to hold onto random walk phase errors from a HP-105 OCXO,
which basically means that it is too weak for real-life use with
such integration times. This is yet to be resolved.
