virtqueue: flexible layout, size, alignment
Transports can now lay out available/used/descriptor
regions in a flexible way.
This is useful for embedded systems to save memory,
and for large systems to reduce the need for
physically-contigious memory.
However, this does not add a way to actually program this
in any of the transports, so it's not useful by
itself, separate follow-up patches will add a way to
program this for transports.
