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().

Before, the `MAX_SEQUENCE_NUMBER` is 65535, such that the logic to get the next
sequence number:

`previousSeqNumber + 1 % MAX_SEQUENCE_NUMBER`

yields 0 when `previousSeqNumber` is 65534. However, the next sequence number
should be 65535.

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.

Simple, initial implementation to allow setResolution()
to set the output height, for downscaling/upscaling.

Per TODOs, follow-up CLs may change layering, add UI,
or allow querying decoders for more resolution options.

Currently, TrackSelectionOverrides are documented as being applied
per track type, meaning that one override for a type disables all
other selections for the same track type. However, the actual
implementation only applies it per track group, relying on the
track selector to never select another renderer of the same type.

This change fixes DefaultTrackSelector to fully adhere to the
TrackSelectionsOverride definition. This solves problems when
overriding tracks for extension renderers (see Issue: google/ExoPlayer#9675)
and also simplifies a workaround added to StyledPlayerView.

The asynchronous MediaCodec adapter queues input buffers in a
background thread. If a codec queueuing operation throws an exception,
the buffer enqueuer will store it as a pending exception and re-throw it
the next time the adapter will attempt to queue another input buffer.

The buffer enqueuer's flush() and shutdown() may throw an exception if
the pending error is set. This is subject to a race-condition in which
the pending error can be set while the adapter is flushing/shutting down
the enqueuer, e.g., if an input buffer is still being queued and the
codec throws an exception. As a result, the adapter cannot flush or
shutdown gracefully.

This change makes the buffer enqueuer to ignore any pending error
when flushing/shuttinf down so that the adapter can flush/release
gracefully even if a queueing error was detected.

The Javadoc of DefaultTrackSelector can be shortened as it's not the
right place to document detailed options of the Player track selection
parameters.

The documentation page about track selection is updated to the new
APIs and extended with most relevant options and information needed
to work with ExoPlayer's track selection API.

MediaSource can be reused with other Player instances after they
have been released, so we need to set the PlayerId when preparing
the source. Access can mostly be handled by the implementation in
BaseMediaSource.

Robolectric uses the JRE HttpURLConnection [1], while real Android
devices and emulators use OkHttp to implement HttpURLConnection. This
can lead to important differences in behaviour, so it's better to use
instrumentation tests when specific HTTP behaviour is important.

The setters in the Builder are already deprecated and using the
old getter is error-prone as they only return the overrides set

The `VideoSamplePipeline` handles all steps from decoding to
re-encoding that where previously in
`TransformerTranscodingVideoRenderer`. The renderer is now only
responsible for reading the format, reading input, passing it to the
pipeline and passing the pipeline's output to the muxer.

When no transformations are needed, decoding and re-encoding is
skipped using the `PassthroughPipeline`.

We can rename the existing setIndex method to a more generic init
as this method is only called by EPII and implemented by BaseRenderer
anyway.
