dccp: Set per-connection CCIDs via socket options
With this patch, TX/RX CCIDs can now be changed on a per-connection
basis, which overrides the defaults set by the global sysctl variables
for TX/RX CCIDs.
To make full use of this facility, the remaining patches of this patch
set are needed, which track dependencies and activate negotiated
feature values.
