Adds debug_cwnd and DEBUG_CWND definitions in config.h to allow closer inspection of ktcp congestion control algorithms for application writes, delayed writes, ACKs, DUP ACKs, showing sequence numbers and inflight and cwnd TCP control variables.

TCP congestion control is being discussed in more detail in #2487 and Mellvik/TLVC#211.
