This puts the window counter computation [RFC 4342, 8.1] into a separate function which is called whenever a new packet is ready for immediate transmission in ccid3_hc_tx_send_packet. Justification: The window counter update was previously computed after the packet was sent. This has two drawbacks, both fixed by this patch: 1) re-compute another timestamp almost directly after the packet was sent (expensive), 2) the CCVal for the window counter is needed at the instant the packet is sent. Further details: The initialisation of the window counter is left in the state NO_SENT, as before. The algorithm will do nothing if either RTT is initialised to 0 (which is ok) or if the RTT value remains below 4 microseconds (which is almost pathological).
