lib: Keep track of highest delivered seqno
The FRCT kept only a left window edge in the receiver connection window, however, it needs to keep track of the left window edge (highest ACK'd sequence number) and the highest delivered sequence number, so it can delay ACKs that cannot be piggybacked. TCP recommends at most 500 ms for delayed ACKs (probably good to keep it near half of RTO).
