tonihei 0a8ae74217 Update DownloadHelper to use MediaSource and MediaPeriod directly.
This requires to prepare the media source and the periods in a small helper similar
to the metadata retriever. It also gets rid of the need to have abstract protected
methods to load the manifest, to extract the track groups and to convert to stream keys,
as this can now be handled by the media period.
