libqos: add VIRTIO PCI 1.0 support
Implement the VIRTIO 1.0 virtio-pci interface. The main change here is
that the register layout is no longer a fixed layout in BAR 0. Instead
we have to iterate of PCI Capabilities to find descriptions of where
various registers are located. The vring registers are also more
fine-grained, allowing for more flexible vring layouts, but we don't
take advantage of that.
