lib: Add support for Linux RTT estimator
This adds the option to use the Round-Trip-Time (RTT) estimation
algorithm as it is implemented in the TCP implementation in Linux. It
looks like it outperforms the TCP default algorithm, so I enabled this
one by default. Also adds the option to change the RTO timeout
calculation to include more (or less) than 4 times the mdev (specified
as a power of 2. Left the default value to 2 (so, 4 mdevs), but 3 (8
mdevs) gives better results in my tests.
