[DCCP]: Allow to parse options on Request Sockets
The option parsing code currently only parses on full sk's. This causes a problem for
options sent during the initial handshake (in particular timestamps and feature-negotiation
options). Therefore, this patch extends the option parsing code with an additional argument
for request_socks: if it is non-NULL, options are parsed on the request socket, otherwise
the normal path (parsing on the sk) is used.
Subsequent patches, which implement feature negotiation during connection setup, make use
of this facility.
