Log:
Now that the private parts of timecounters are no longer being fingered
by other bits of code, split struct timecounter into two.
Please let me know if you see any changes in timekeeping behaviour
as a result of this series of commits.
Given the fact that I'm running xntpd and it syncs the clock with a
known good source while online, is it possible that any problems might
get `hidden' by xntpd resetting the clock before it runs too different
from a correct value? That is, should I disable ntpd for a while?
