gre: Add netlink interface
This patch adds a netlink interface that will eventually displace the existing ioctl interface. It utilises the elegant rtnl_link_ops mechanism. This also means that user-space no longer needs to rely on the tunnel interface being of type GRE to identify GRE tunnels. The identification can now occur using rtnl_link_ops.
