The qos stuff belongs to qtest, so move it into that directory, too.

There was no real virtio-mmio ABI change between Legacy and VIRTIO 1.0
except that the Version field was incremented from 1 to 2.
However, QEMU does not allow Legacy drivers to perform VIRTIO 1.0
operations like accessing 64-bit feature bits. Since we will introduce
64-bit feature bit support we need a way to differentiate between
virtio-mmio Version 1 and 2 to avoid upsetting QEMU when we operate in
Legacy mode.
Stash away the Version field so later patches can change behavior
depending on the version.

Add virtio-mmio node in qgraph framework.
virtio-mmio produces virtio-bus, the interface consumed by all virtio-*-device
nodes.
Being a memory-mapped device, it doesn't have to provide a constructor
to qgraph, since it's always "contained" inside some other nodes.
