- 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.

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.

Functionality is moved into Eia608Parser, so that Eia608Parser
can be used with TextTrackRenderer, similar to all the other
text/subtitle formats. Modified some of the other
text/subtitle-related classes to support the new behaviour.

prepare(SampleSource) is renamed to setSource(SampleSource). The player
immediately transitions to STATE_BUFFERING when the source is set, at which
point doSomeWork is called.

TrackRenderer and SampleSourceTrackRenderer both now use a TrackStream
so they can be merged.
(This may also be useful for adding playlist support, in case TrackStreams need
to be replaced during playback.)

FrameworkSampleSource will still be useful for audio, where
sample interleaving isn't an issue. We could optionally add
a "don't wait for first frame" boolean to the video renderer
if we *really* need to keep some form of this workaround in
place, but I'd rather not do so for now.

GitHub note - Apologies for the cryptic change descriptions,
they relate to a design doc that's not externally visible.

When a seek is performed, renderers currently perform the
actions that they need to take in two places: Some changes
are performed in seekTo implementations. Other changes are
performed when discontinuities are read from the source.
In HLS we need to perform what is effectively a seek
originating in the source. To support this, this CL allows
discontinuities read from the source to modify the playback
position. All actions that renderers perform as a result
of a seek are moved to be performed when a discontinuity is
received.
Best way to understand CL:
- Look at SampleSource interface change and then at the
concrete implementations, to make sure they've been
changed properly.
- Look at SampleSourceTrackRenderer change.
- Look at concrete renderers. The general pattern is that
code previously performed in seekTo and READ_DISCONTINUITY
is merged into onDiscontinuity().
Note: This will be further untangled in V2.

Currently, input/output buffers can 'leak' if they are dequeued then the decoder
is flush()ed. This happens if an input buffer is dequeued then a discontinuity
is read, or an output buffer is dequeued and is early. If this happens several
times, no more buffers are available.
This change makes flush() work like MediaCodec: it returns all dequeued
input/output buffers to the codec. Keeping the behavior in line with MediaCodec
might make it easier to factor out a common decoder interface in the future.
