Let's implement support for abstract virtio based memory devices, using the virtio-pci implementation as an orientation. Wire them up in the machine hotplug handler, taking care of s390x page size limitations. As we neither support virtio-mem or virtio-pmem yet, the code is effectively unused. We'll implement support for virtio-mem based on this next. Note that we won't wire up the virtio-pci variant (should currently be impossible due to lack of support for MSI-X), but we'll add a safety net to reject plugging them in the pre-plug handler.
