History
phk 044e1e6296 Replace TOD clock code with more systematic approach. 
Highlights:
    * Simple model for underlying hardware.
    * Hardware basis for timekeeping can be changed on the fly.
    * Only one hardware clock responsible for TOD keeping.
    * Provides a real nanotime() function.
    * Time granularity: .232E-18 seconds.
    * Frequency granularity:  .238E-12 s/s
    * Frequency adjustment is continuous in time.
    * Less overhead for frequency adjustment.
    * Improves xntpd performance.
