[timekeeper] Final Kalman Filter changes in prep for frequency.

* Receive samples by reference rather than value (since they also need
  to go to the frequency estimator).
* Return the change in estimate from accepting a new sample.
* Use the frequency when building a transform.
* Define a new function to modify the frequency.
