hw/virtio: add config support to vhost-user-device
To use the generic device the user will need to provide the config
region size via the command line. We also add a notifier so the guest
can be pinged if the remote daemon updates the config.
With these changes:
-device vhost-user-device-pci,virtio-id=41,num_vqs=2,config_size=8
is equivalent to:
-device vhost-user-gpio-pci
