We let the specifics of the ring format seep through to vhost API
callers - mostly because there was only one format so it was
hard to imagine what an independent API would look like.
Now that there's an alternative in form of the packed ring,
it's easier to see the issues, and fixing them is perhaps
the cleanest way to add support for more formats.
This patchset does this by indtroducing
