Display status names instead of bitmaps for VirtIODevice. Display feature names instead of bitmaps for backend, protocol, acked, and features (hdev->features) for vhost devices. Decode features according to device type. Decode status according to configuration status bitmap (config_status_map). Decode vhost user protocol features according to vhost user protocol bitmap (vhost_user_protocol_map). Transport features are on the first line. Undecoded bits (if any) are stored in a separate field. Vhost device field wont show if there's no vhost active for a given VirtIODevice.
