Based on Rusty's patches. Coding style and funny jokes are his. Bugs and a star wars reference (should be easy to spot) are mine. Untested, but useful as basis for beginning the qemu work. TODO: = simplify probing: use a common probe function, probe with modern driver first, if that fails - probe with legacy driver. BUGS: ATM legacy driver can win and drive a transitional device

This is on top of 3.19 master + my bugfix patches, and adds virtio 1.0 support to virtio pci. This is 3.20 material I think. Would like to get feedback on s390 change as it's untested.
