skips ring accesses but drops out of order support At high level this follows alf design https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/lib/alf_queue.c but on most (single-threaded) benchmarks this seems to be slower than the layout without index use.

This adds micro-benchmarks useful for tuning virtio ring layouts. Three layouts are currently implemented: - virtio 0.9 compatible one - an experimental extension bypassing the ring index, polling ring itself instead - an experimental extension bypassing avail and used ring completely Typical use: sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring It doesn't depend on the kernel
