android: CameraDevice: Return const shared_ptr& by camera()
CameraDevice::camera() originally returns shared_ptr. It is mandatory to make a copy by calling camera() in this way. There is no need of copying if a caller needs the reference of the camera like const shared_ptr<Camera> &cam = camera(). That is, it is a caller that copying is required. This changes the return type of camera() to const shared_ptr&, so that we are able to reduce one redundant copy in the above case.

 * Once started the timer will run until it times out. It can be stopped with
 * stop(), and once it times out or is stopped, can be started again with
