Document that apps should retain `GlUtil.Program` while the program is in use,
and keep a reference to attributes/uniforms within the program to make sure
they don't get GC'd causing any allocated buffers passed to GL to become
invalid.

Tested manually by running gldemo and transformer.

The features supported by `TranscodingTransformer` are a
superset of those supported by `Transformer` after merging
the video renderers in <unknown commit>. This change removes
`TranscodingTransformer` and adds its features to `Transformer`.

Follow-up to a comment on https://github.com/google/ExoPlayer/commit/6f0f7dd1be40c81cb056d82215ceabdd5a8a2a1a: Buffers that are useful to pass
to the sample/passthrough pipeline should either contain data or the
end of input flag. Otherwise, passing these buffers along is unnecessary
and may even cause the decoder to allocate a new input buffer which is
wasteful.

The player will not play ads in final states (played, skipped, error)
again. To allow ads loader customizations to play ads again, we can
add a method that resets the state back to available or unavailable
(depending on whether we have the URI for the ad).

Currently, DrmSessionManager takes player specific values (= the
playback looper) through (pre)acquireSession calls and requires
the caller to pass in the same values every time.

Instead, we can configure the DrmSessionManager for playback with
a player once before it's being used. We can't simply extend the
prepare() method as prepare may be called before the player is
created to prewarm the DrmSessionManager.

The new method also takes a PlayerId which is bound to the lifetime
of the player similar to the playback looper.

To avoid breakage of custom MediaSources with DRM, we can keep the
old the SampleQueue.createWithDrm method as deprecated.

There has been many issue recently about tunneling
that have no obvious solutions and we don't have the
bandwidth to dive into the platform root cause.

The `SefSlowMotionVideoSampleTransformer` drops frames by
setting `buffer.data = null` and updates the timestamps of the
frames it keeps. However, these buffers with dropped frames
are still used in the pipeline as they may contain other useful
information, specifically whether the end of the input has been
reached. So, the timestamps should also be updated for the buffers
where frames are dropped.

StyledPlayerControlView can't really be used on its own (like
PlayerControlView was used here), so we instead use the same
StyledPlayerView instance for both local and casted playback,
replacing the content with a cast icon while casting.

The local tracks variable was used to assign the initial subtext
for the current track selection in the menu, but the new value
was only assigned after the subtext has been evaluated.

Assign the local variable first, so that the remaining accesses
the latest value.

We verified there is a race condition in the
AsynchronousMediaCodecAdapter when flushing the adapter
multiple times. The race condition results in calling MediaCodec.start()
and MediaCodec.flush() in parallel and that makes the MediaCodec
raise an exception.

This changes the default behavior to call MediaCodec.start() on the
same thread after MediaCodec.flush() to avoid the race condition.

Populate ICY headers into MediaMetadata so that they can
propagate to the app via AnalyticsListener#onMediaMetadataChanged().
This change copies IcyHeaders.name into MediaMetadata.description
and IcyHeaders.genre into MediaMetadata.genre.

Note: MediaItem.metadata maintain their precedence and overwrite any
ICY headers parsed.

In the near future, we will be able to specify which tests run on this
target explicitly, at which point this ignore will be removed.

The `GlUtil` wrappers for attributes/uniforms allocate buffers that are passed into OpenGL, and it seems that the distorted output was caused by these buffers being garbage collected.

The issue was difficult to reproduce manually. Add a test that does repeated transcodes in a loop (marked `@Ignore` for now because it runs for a long time and requires network access so may be flaky) to make it easier to run many transcodes and look for inconsistent output. For now the consistency check is just based on the file size which is very likely to change if the actual video frames change.

Verified that the test fails before, and passes once the attributes and uniforms are stored in fields as in this CL.

This change merges `TransformerMuxingVideoRenderer` and
`TransformerTranscodingVideoRenderer` into `TransformerVideoRenderer`.
Besides all features supported by `TransformerTranscodingVideoRenderer`
the new merged `TransformerVideoRenderer` also supports SEF slow motion
flatting without re-encoding like the `TransformerMuxingVideoRenderer`.
To do this, it uses a `SefSlowMotionVideoSampleTransformer` with
the `PassthroughPipeline`.

This mime type is technically for the Muxer, and determines
the container used. In the context of the transformer, this can
be thought of more as a container mime type, to avoid confusion
with the video mime type and audio mime type.

Deprecates setOutputMimeType().
