Using descriptors in-order is sometimes benefitial. Add an option for
that - per-format detail allowing more optimizations will be added by
follow-up patches.

Performance analysis of this is in my kvm forum 2016 presentation. The
idea is to have a r/w descriptor in a ring structure, replacing the used
and available ring, index and descriptor buffer.
This is also easier for devices to implement than the 1.0 layout.
Several more enhancements will be nece
