Richard Cochran 10753faccf Implement the synchronization events. 
This will allow a port to get from the uncalibrated into the slave state.

Richard Cochran ecf959ce3d Reject negative path delay. 
If the path delay comes out negative, then something is amiss. In this
case, we just print a warning and ignore the path delay estimate.

Richard Cochran 87e61f9770 Let the clock servo know about the expected time stamp quality. 
If software time stamping is to be used, then the servo will want to
have appropriate filtering.

Richard Cochran 56a5adc1cc Smooth the path delay estimate with a moving average. 
This is really just a first attempt using a hard coded length. Probably
it will be necessary to let the length be configurable and/or adaptable.

Richard Cochran ebd353aff6 Link it all together, but in slave-only mode. 
Since the master implementation is still lacking, we will just keep
the slave-only flag hard coded for now.
