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().

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.

The decoder writes to `OpenGlFrameEditor`'s input `Surface`
and the `OpenGlFrameEditor` writes to the encoder's input `Surface`.

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`.

When dropping the remainder, the decoder and encoder timestamps start diverging after a few buffers when no speed changes are supposed to occur. Tracking the remainder keeps them in sync.

* Remove GlUtil.Program String[] constructor to unify and just use the
String constructor.
* Add getAttributeArrayLocationAndEnable() to simplify things a tiny bit.
* Increase usage of constant values.

`TransformerAudioRenderer` reads input and passes `DecoderInputBuffer`s
to the `AudioSamplePipeline`. The `AudioSamplePipeline` handles all
steps from decoding to encoding. `TransformerAudioRenderer` receives
`DecoderInputBuffer`s from the `AudioSamplePipeline` and passes their
data to the muxer.
`AudioSamplePipeline` implements a new interface `SamplePipeline`.
A pass-through pipeline will be added in a future cl.

If the number of samples changes, the sizes will help us to verify
whether they are just split differently or extra data was added.

This helps to prevent issues where decoders can't handle negative
timestamps. In particular it avoids issues when the media accidentally
or intentionally starts with small negative timestamps. But it also
helps to prevent other renderer resets at a later point, for example
if a live stream with a large start offset is enqueued in the playlist.

`checkNotNull` should be avoided where possible.
This change adds `@EnsuresNonNull` or `@EnsuresNonNullIf` to configuration methods for fields they initialize.
`checkNotNull` is now avoided for the `@MonotonicNonNull` formats by adding `@RequiresNonNull` annotations.
`checkNotNull` is now avoided for the encoder and decoder in `feedMuxerFromEncoder()`, `feedEncoderFromDecoder()`, `feedDecoderFromInput()`, etc. by creating local variables for `encoder` and `decoder` in `render` after the configuration method calls and passing these as non-null parameters.
