I agree that it would be very helpful to be able to access the
negotiated features via the monitor, but I disagree with your approach,
especially the need to expose every single feature bit via a property.

What about a command like 'info virtio' instead? This would allow us to
dump not only guest features, but the host features initially offered
alongside them and things like the status byte (so you can actually
check whether feature negotiation was successful). Maybe similar to
'info block'.
