[DCCP] CCID2: Halve cwnd once upon multiple losses in a single RTT
When multiple losses occur in one RTT, the window should be halved only once [a single "congestion event"]. This is now implemented, although not perfectly. Slightly changed the interface for changing the cwnd: pass hctx instead of dp. This is required in order to allow for change_cwnd to be called from _init().
