Delio Brignoli bd001fdec7 port: adjust peer delay calculation using neighborRateRatio
Previouly the peer delay was not taking into account the
frequency offset between the local clock and the peer's clock.
Reset neighborRateRatio to 1.0 in port_nrate_initialize().

Richard Cochran 8f5bd0edda Guard against divide by zero.
If a buggy driver or hardware delivers bogus time stamps, then we might
crash with a divide by zero exception.

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.
