  virtio: don't set VIRTIO_CONFIG_S_DRIVER_OK twice. (2015-02-17 16:19:29 +1030)

----------------------------------------------------------------
OK, this has the big virtio 1.0 implementation, as specified by OASIS.

On top of tht is the major rework of lguest, to use PCI and virtio 1.0, to
double-check the implementation.

Then comes the inevitable fixes and cleanups from that work.

Thanks,
Rusty.
