[DCCP]: Prepare the AF agnostic core for the introduction of DCCPv6
Basically exports a similar set of functions as the one exported by the non-AF specific TCP code. In the process moved some non-AF specific code from dccp_v4_connect to dccp_connect_init and moved the checksum verification from dccp_invalid_packet to dccp_v4_rcv, so as to use it in dccp_v6_rcv too.
