lib: Add initial rtt estimator to FRCT
This adds a simple round-trip time estimator to FRCT. The estimate is
a weighted average with deviation. The retransmission is scheduled
after rtt + 2 times the deviation. A retransmit doubles the rtt
estimate to avoid the no-update case when rtt suddenly increases. The
rtt is estimated in microseconds and the granularity for retransmits
is 256 microseconds.
