Extend virtio to support many interrupt vectors, and rearrange code in preparation for multi-vector support (mostly move reset out to bindings, because we will have to reset the vectors in transport-specific code). Actual bindings in pci, and use in net, to follow. Load and save are not connected to bindings yet, so they are left stubbed out for now. Signed-off-by: Michael S. Tsirkin <mst at
