dccp: Integrate feature-negotiation insertion code
The patch implements insertion of feature negotiation at the server (listening
and request socket) and the client (connecting socket).
In dccp_insert_options(), several statements have been grouped together now
to achieve (I hope) better efficiency by reducing the number of tests each
packet has to go through:
- Ack Vectors are sent if the packet is neither a Data or a Request packet;
- a previous issue is corrected - feature negotiation options are allowed
on DataAck packets (5.8).
