lstewart 1c7932d870 - Provide a sysctl interface to change the active system clock at runtime. 
- Wrap [get]{bin,nano,micro}[up]time() functions of sys/time.h to allow
  requesting time from either the feedback or the feed-forward clock. If a
  feedback (e.g. ntpd) and feed-forward (e.g. radclock) daemon are both running
  on the system, both kernel clocks are updated but only one serves time.

- Add similar wrappers for the feed-forward difference clock.

Committed on behalf of Julien Ridoux and Darryl Veitch from the University of
Melbourne, Australia, as part of the FreeBSD Foundation funded "Feed-Forward
Clock Synchronization Algorithms" project.
