tcp: Improve RFC3517bis support

- Factor out tcp_fast_recovery()
- Delay fast retransmit or fast recovery for duplicated ACK which
  carries data or updates receiving window, so that
  o  The segments sent by fast retransmit/recovery could carry
     proper ack sequence and SACK information.
  o  Receiving window could get updated, so more new data could be
     injected into the network by the fast recovery.
