dccp: Per-socket initialisation of feature negotiation
This provides feature-negotiation initialisation for both DCCP sockets
and DCCP request_sockets, to support feature negotiation during
connection setup.
It also resolves a FIXME regarding the congestion control
initialisation.
Thanks to Wei Yongjun for help with the IPv6 side of this patch.
