AudioService: alternative way of handling device rotation

For devices that monitor orientation (primarily for channel assignment
 to stereo speakers):
The com.android.server.policy.WindowOrientationListener API is more
 power efficient than simply monitoring the device's orientation. When
 supported, use it instead of android.view.OrientationEventListener.
When WindowOrientationListener reports an orientation change, start
 a thread to poll the UI orientation, as its change may lag behind
 the observed rotation. Gradually increasing delays between polls
 are stored in a table.
