Introduce VIRTIO_RING_NO_LEGACY to support disabling legacy macros and layout definitions. Suggested-by: Michael S.

There's a single commit here that I tweaked since linux-next - the change is in printk format string which I consider trivial enough not force wait for more testing. A couple of hashes are different from what's in linux-next though. I also upgraded the machine I used to sign the tag (didn't change the key) - hope the signature is still ok. If not pls let me know!

struct vring (in the uapi directory) and supporting APIs are kept around to solely avoid breaking old userspace builds. It's not actually part of the UAPI - it was kept in the UAPI header by mistake, and using it in kernel isn't necessary and prevents us from making changes safely. In particular, the APIs actually assume the legacy layout. Add an internal kernel-only struct vring and
