Edward Hervey af78c16dd5 New HLS, DASH and MSS adaptive demuxer elements
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.
