About +/- 0, I am not sure which!

I will get back around to it. There are 2 sets of changes. In PTP itself a
change is to add kqueue support because select in libbsd does not support
signals. The PTP code runs a number of timers and they run of an alarm signal.
The other piece of support is to the score to bring in the FreeBSD kern_ntp
support to sit besides the timercounters.

There will be some unresolved issues like RTC driver support. I have this
commented out as I do not need it.

I would like to upstream the code however adding kqueue will trip that interface
on FreeBSD and may be others so I am not sure how much work that will create.
