IPVS: Add internal versions of sockopt interface structs
Add extended internal versions of struct ip_vs_service_user and struct ip_vs_dest_user (the originals can't be modified as they are part of the old sockopt interface). Adjust ip_vs_ctl.c to work with the new data structures and add some minor AF-awareness. Signed-off-by: Julius Volz <juliusv@google.com> Signed-off-by: Simon Horman <horms@verge.net.au>
