According to the spec, there is no mandatory relation between segments'
sequence numbers of different variants. This CL ignores sequence numbers
when switching variants:
* In vod, the switching playback position is obtained by adding the
duration of previous segments.
* In live playback this is not possible. It is assumed that the
different live media playlists do not drift apart too much, so
the playback position is obtained by subtracting the duration
in reverse order.
In later CLs, the described mechanisms will become the fallback methods
by replacing them with the use of EXT-X-PROGRAM-DATE-TIME information
or more reliable sources.

With this change, MediaCodecRenderer acquires a session
from its DrmSessionManager whenever the DrmInitData in
the format changes. The DrmSessionManager is permitted
to return the same session if it can be re-used.
This plumbing adds support for:
1. Key-rotation, in the case that a key-rotation-aware
DrmSessionManager is used. Such an implementation will
return the same DrmSession for every aquisition, but
will be making use of multiple MediaDrm instances within
that session to enable the rotation.
2. Playlists with mixed clear and protected content. One
final piece to this will be to have each MediaPeriod
provide its own license URL. We could also allow each
MediaPeriod to specify the DRM UUID, but switching from
PlayReady to Widevine in a playlist seems like quite a
hypothetical thing.

In V1 we received complaints that Renderer was too locked down.

At a high level, everything that we need to load in sync

* Add a selection policy for video (probably related with adaptiveness).
* We should decide what to do with the default flag.
* Perhaps, if no audio with the preferred language(assuming there is one)
is found, we should fall back to a text track that has the preferred
language.

1. Properly split out listening responsibilities so that
DemoPlayer only listens to its own components.
2. Revert StreamingDrmSessionManager UnsupportedDrmScheme
exceptions back to how they worked in V1, and inject
a DrmSessionManager rather than a MediaDrmCallback into
DemoPlayer.
This much better prepares DemoPlayer for promotion into
the core ExoPlayer library, since it removes assumptions
such as what SampleSource and DrmSessionManager impls
might be used with it.

Now [DASH/SS]SampleSource instances are creating ChunkTrackStream

- 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.

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.

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.

Reading the format and/or a sample needs to be done as a
single operation. Else you can have a situation where the
queue is initially empty, and this happens:
1) Read downstream format X
2) Read downstream format X (unchanged)
3) Write format Y
4) Write first sample
5) Read first sample
The first sample then appears to be format X rather than Y.
Note that readData in the SampleSource implementations always
looks roughly the same. readReset is identical in all cases.
isReady is identical in all cases now I've fixed them to be
that way. So it should be pretty easy to get DefaultTrackOutput
to implement TrackStream directly, at which point a whole load
of duplication will disappear.

At this point the only reason preventing the chunk package

over to using a single RollingSampleBuffer per track, with
the splicing done inline.
