Added new GSO type for USO: VIRTIO_NET_HDR_GSO_UDP_L4. Feature VIRTIO_NET_F_HOST_USO allows to enable NETIF_F_GSO_UDP_L4. Separated VIRTIO_NET_F_GUEST_USO4 & VIRTIO_NET_F_GUEST_USO6 features required for Windows guests.

I think it's better to be consistent here. Either we split in both guest and host or not. Thanks
