Make the fbclock_[get]{bin,nano,micro}[up]time() function prototypes public so
that new APIs with some performance sensitivity can be built on top of them. These functions should not be called directly except in special circumstances. 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. For more information, see http://www.synclab.org/radclock/ Discussed with: Julien Ridoux (jridoux at unimelb edu au) Submitted by: Julien Ridoux (jridoux at unimelb edu au)
