This integrates feature-activation in the client, with these details:
1. When dccp_parse_options() fails, the reset code is already set, request_sent
_state_process() currently overrides this with `Packet Error', which is not
intended - so changed to use the reset code set in dccp_parse_options();
2. There was a FIXME to change the error code when dccp_ackvec_add() fails.
I have looked this up and found that:
* the check whether ackno < ISN is already made earlier,
* this Response is likely the 1st packet with an Ackno that the client gets,
* so when dccp_ackvec_add() fails, the reason is likely not a packet error.
3. When feature negotiation fails, the socket should be marked as not usable,
so that the application is notified that an error occurs. This is achieved
by a new label, which uses an error code of `Aborted' and which sets the
socket state to CLOSED, as well as sk_err.
4. Avoids parsing the Ack twice in Respond state by not doing option processing
again in dccp_rcv_respond_partopen_state_process (as option processing has
already been done on the request_sock in dccp_check_req).
Since this addresses congestion-control initialisation, a corresponding
FIXME has been removed.
