Camera2: Fire all callbacks
- Allow configureOutputs to be called when device is
actively working, and document what happens then.
- At the managed level, trigger proper sequence of callbacks for
device state changes, for all the callbacks that are not yet
managed by the camera service.
- Restructure CameraManager.openDevice to have the device itself fire the
initial callbacks.
- Make CameraDevice.configureOutputs(null) work.
- Make CameraDeviec.configureOutputs(identical surfaces) work.
- Ensure proper checking for camera closed state.
