This provides new HLS, DASH and MSS adaptive demuxer elements as a single plugin. These elements offer many improvements over the legacy elements. They will only work within a streams-aware context (`urisourcebin`, `uridecodebin3`, `decodebin3`, `playbin3`, ...). Stream selection and buffering is handled internally, this allows them to directly manage the elementary streams and stream selection.
