They're current location is annoying, because it creates a dependency
from the dash package to the webvtt package. For apps like Play Movies
where WEBVTT isn't used, it's nice just to delete the whole package at
import time, which requires that this dependency be removed.

MIME type of audio/raw. Remove Ac3PassthroughAudioTrackRenderer,
which is no longer used.
Plus start to properly document the SmoothStreaming package.
Note that where the documentation is a little vague, this is

vague!

(i.e. ManifestFetcher) to the Parser level (i.e. ManifestParser).
- The motivation here is to allow the implementation of components that
can work with a generic ManifestParser implementation.
