9efa32e49b Accumulate remainder in buffer duration calculations.
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.

8552345f8f Add PassthroughSamplePipeline for audio.
When no transformation is needed, the passthrough pipeline allows us to skip decoding and re-encoding.

62a35018f8 Separate TransformerAudioRenderer and new AudioSamplePipeline.
`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.

49a93e31d7 Write sample size to dumpfile in transformer tests.
If the number of samples changes, the sizes will help us to verify whether they are just split differently or extra data was added.

c3bce234ca Improve format propagation in transformer
- Store output format in `MediaCodecAdapterWrapper` when we get a format from
  the codec, instead of creating it on demand.
- Make format building code not audio-specific.
- Remove `MediaCodecAdapterWrapper.getConfigFormat` and instead keep track of
  the input/output formats in the renderer. This will mean that the code still
  works if an audio processor changes the audio format in future.
- Make exceptions thrown during audio rendering use the same (input) renderer
  format.
- Misc other minor cleanup.
