this patch modifies the pi servo to add a configurable max offset (default
infinity). When ever the detected offset is larger than this value, the clock
will jump and reset the servo state. The value of this feature is for decreasing
time to stabalize when clock is off by a large ammount during late running. This
can occur when the upstream master changes, or when the clock is reset due to
outside forces. The method used to reset clock is simply to reset the pi servo
to the unlocked state.

If software time stamping is to be used, then the servo will want to
have appropriate filtering.
