Summary: This change introduces an OrientationSensor class which wraps a QOrientationSensor. The OrientationSensor is hold by Screens and gets enabled if Screens knows about an internal (e.g. LVDS) display which supports rotation. In addition the OrientationSensor holds an KSni to enable/disable the automatic rotation support. The drm platform plugin is adjusted to make use of the OrientationSensor. The API is defined in a way that this can also be implemented on other platforms supporting rotation. Most important are hwcomposer and X11 standalone. The latter should be straight forward as rotation is provided through XRandR. The former needs addition for rotation support first.
