- Add the ffclock_getcounter(), ffclock_getestimate() and ffclock_setestimate()

  system calls to provide feed-forward clock management capabilities to
  userspace processes. ffclock_getcounter() returns the current value of the
  kernel's feed-forward clock counter. ffclock_getestimate() returns the current
  feed-forward clock parameter estimates and ffclock_setestimate() updates the
  feed-forward clock parameter estimates.

- Document the syscalls in the ffclock.2 man page.

- Regenerate the script-derived syscall related files.

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.
