net: implement a SO_DOMAIN getsockoption
This sockopt goes in line with SO_TYPE and SO_PROTOCOL. It makes it possible for userspace programs to pass around file descriptors — I am referring to arguments-to-functions, but it may even work for the fd passing over UNIX sockets — without needing to also pass the auxiliary information (PF_INET6/IPPROTO_TCP).
