This also deletes unused features of the video_capturer interface, the classes VideoCaptureFeedBack, VideoCaptureEncodeInterface and related methods, and the module id which used to be passed as an argument to the VideoCaptureDataCallback. In theory the module id could have been used to let a single VideoCaptureDataCallback serve several capturers, and demultiplex on the id, but in practice, it was unused. With this change, it is required to use a separate VideoSinkInterface for each capturer.
