We now download fragments as fast as possible and push them downstream while another thread is just responsible for updating live playlists every now and then. This simplifies the code a lot and together with the new buffering mode for adaptive streams in multiqueue makes streams start much faster. Also simplify threading a bit and hopefully make the GstTask usage safer.
