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.
