    libxl: Add device_{config,type} to libxl__ao_device
    
    These two fields help to give more information about the device been
    hotplug/hotunplug to callbacks.
    
    There is already `dev' of type `libxl__device', but it is mostly
    useful when the backend/frontend is xenstore. Some device (like
    `usbdev') don't have devid, so `dev' can't be used.
