VIRTIO_F_NOTIFICATION_DATA: extra data to devices
Some devices benefit from ability to find out the number of available
descriptors in the ring: for efficiency or as a debugging aid.
To help with these optimizations, add a new feature:
VIRTIO_F_NOTIFICATION_DATA. When negotiated, driver notifications to the
device include this extra information.
