The FFmpeg extension can support various different MIME types, so pass the
whole format to configure the decoder.

When skipToData is called the peek position is not equal
to the read position of the input. Hence peeking a chunk
header and then skipping by that amount wont do the right
thing :)!

Mechanical step to create a new HlsSource in the library.
Note that naming is now confusing. This will be fixed in
the next CL, when:
HlsSource -> HlsSampleSource
HlsSampleSource+HlsOutput -> HlsOutput

- This means DrmInitData is propagated through sample queues (i.e.
is effectively attached to every sample, so we can see when it
changes when reading from the queue).
- It also allows different DrmInitData per track, which is possible
in muxed MKV/WebM, and per Representation for DASH, although we
wont be able to seamlessly adapt in the latter case.

I've seen a sample that has a LIST chunk prior to fmt. It
seems best just to skip all chunks until the format is
located. As per the RIFF spec:
"Programs must expect (and ignore) any unknown chunks
encountered, as with all RIFF forms."

This allows limiting the horizontal extension of the cues.
NOTE: So far, we only support percentages for size magnitudes.

SubtitleParser includes a method updating the current
playback position for parsers that need to be aware
of the position in order to determine how to batch
captions (i.e. Eia608Parser).

- This moves to a single DrmInitData implementation that supports
both specific and universal UUID matching. You can also do a
combination of the two, which was not previously possible.
- The object model is simplified as a result. This is a precursor
to a change where DrmInitData will be included directly in the
Format to enable key rotation.

In order to apply track type specific policies in
the track selection, we need to know the type of
the track renderer, this method returns one of the
constants defined in C.java of the form TRACK_TYPE_*
to allow renderer classification.

If the media format changes from one Format object to another
one that's is equal (but not the same object), readData would
end up performing an expensive equality evaluation on every
invocation.

This will be required for key rotation to work, since
we'll need a way to determine whether or not the init
data has changed.

Dash/SS SampleSources now instantiate ChunkSource and
ChunkSampleSource (renamed to ChunkTrackStream) instances
on demand as tracks are enabled. The TrackGroups exposed
by the DASH/SS SampleSources are now constructed at the
top level.
Note that this change resolves the TODOs at the top of the
ChunkSource classes, allowing multiple adaptation sets of
the same type.
Next steps will include:
- Bring back UTC timing element support for DASH, which
will be an extra request during preparation in the DASH
SampleSource.
- Simplification of manifest fetching to use a Loader directly
in the two top level SampleSource classes. ManifestFetcher
should eventually go away once HLS no longer needs it.
- Eventually, some consolidation between DASH/SS. There's a
lot of common code there now.

This change pulls manifest refresh responsibility up to the
top level Dash/SS SampleSource implementations. In following
steps more of the manifest processing logic will be pulled
up (e.g. extracting track groups from the initial manifest),
which will allow ChunkSampleSource/ChunkSource instances to
be further simplified and created on demand.
I've avoided moving/renaming anything for now, so as to keep
it fairly easy to review.
Note that this change does the TODO related to releasing the
manifest fetchers.

This is a mechanical change. The two new SampleSource classes
are forked from MultiSampleSource, with the logic that previously
was in the demo app's SourceBuilder methods copied into the
corresponding constructors. Subsequent steps will:
1. Pull the initial manifest processing from DashChunkSource and
SmoothStreamingChunkSource into the new SampleSource classes.
2. Remove the construction of ChunkSampleSource instances from
the constructors, instead instantiating children only as needed
when tracks are enabled.
3. Simplify ChunkSampleSource down into a ChunkTrackStream object.
