This timeline will be used in unit test cases of follow-up
CLs. It basically can be used to emulate the timeline created by a
multi-period live media source when the real time advances.

Playback parameter signalling can be quite complex because
 (a) the renderer clock often has a delay before it realizes
     that it doesn't support a previously set speed and
 (b) the speed set on media clock sometimes intentionally
     differs from the one surfaced to the user, e.g. during
     live speed adjustment or when overriding ad playback
     speed to 1.0f.

This change fixes two problems related to this signalling:
 1. When resetting the media clock speed at a period transition,
    we don't currently tell the renderers that this happened.
 2. When a delayed speed change update from the media clock is
    pending and the renderer for this media clock is disabled
    before the change can be handled, the pending update becomes
    stale but it still applied later and overrides any other valid
    speed set in the meantime.

Both edge cases are also covered by extended or new player tests.

Following test cases are added:
1. Mux H264 video
2. Mux H265 video
3. Mux HDR video

Each test case performs following actions:
1. Extract track and samples from input Mp4 using MediaExtractor.
2. Feed those samples into Mp4 muxer.
3. Use extractor to extract the samples from muxed file and create dump file.

MediaCodecRenderer currently has two independent paths to trigger
events at stream changes:
 1. Detection of the last output buffer of the old stream to trigger
    onProcessedStreamChange and setting the new output stream offset.
 2. Detection of the first input buffer of the new stream to trigger
    onOutputFormatChanged.
Both events are identical for most media. However, there are two
problematic cases:
  A. (1) happens after (2). This may happen if the declared media
     duration is shorter than the actual last sample timestamp.
  B. (2) is too late and there are output samples between (1) and (2).
     This can happen if the new media outputs samples with a timestamp
     less than the first input timestamp.

This can be made more robust by:
 - Keeping a separate formatQueue for each stream to avoid case A.
 - Force outputting the first format after a stream change to
   avoid case B.

Some devices were reported to have wrong PerformancePoint sets
that cause 60 fps to be marked as unsupported even though they
are supported.

The output info for a new stream is marked pending until the last
sample of the previous stream has been processed. However, this fails
if the previous stream has already been fully processed. We need to
detect this case explicitly to avoid signalling the output change one
sample too late.

This test became flaky after https://github.com/google/ExoPlayer/commit/cbb6878f9fef20ea440c6ffda77dd4edc00ce1f2 because some of the
unrealistic frame times ended up on the same release time.

Using realistic numbers avoids the flakiness.

Uses the first mediaItem's format as the output format.

If there is `Presentation` supplied in the `Composition.effects`, add it as the
last effect of the first EditedMediaItem.

Also remove @WorkerThread annotations, as static checks associated with
this annotation aren't useful in this part of the codebase because
almost no methods are called on the main thread.

This change should be a no-op.

We need to use this class in muxer's robolectric and instrumentation tests, hence moving it to test-util module.

Currently if releasing a shader program throws we don't release the GL
context, which could leak resources, and any errors are silently dropped
as we suppress notifications during releasing.

Improve resource cleanup and debuggability of errors from custom effects
by continuing to release shaders on failure (for runtime and
`VideoFrameProcessingException`s) and always clean up the GL context.

Note: this doesn't help with the case where releasing a custom shader
blocks for a long time, causing releasing the frame processor to
time out.

Add format codec info, which can make test skipping checks more similar to the
actual Transformer decoder checks.

Also for the test file, the actual format was 720p, but somehow the file name and
media metadata indicated 1080p. This format mismatch led to some decoding errors,
so fix the format (and associated errors). This also allows us to remove the
exception catch in ForceInterpretHdrVideoAsSdrTest, which was included due to
errors from the incorrect format.

The current logic uses manual array operations to keep track of pending
changes. Modernize this code by using an ArrayDeque and a data class.
This also allows to extend the output stream information in the future.

This also fixes a bug where a position reset accidentally assigns a pending
stream offset instead of keeping the current one.

In most cases, this means updating Subject subclasses and their assertThat methods to accept null actual values. (They should always accept null so that assertions like "assertThat(foo).isNull()" succeed instead of throwing NullPointerException.)

Occasionally, it involves other changes, like writing `isGreaterThan(1L)` instead of `isGreaterThan(1)` to resolve an ambiguity it Kotlin overload resolution.

- Split the transmux setting into transmuxAudio and transmuxVideo. This
  is more flexible for apps and will also be useful for unit testing
  (particularly as we can't test video transcoding on Robolectric at the
  moment).
- Move these settings to Composition. It makes sense for these settings
  to be next to forceAudioTrack. Apps may also want to set these
  settings based on the current Composition's MediaItems.
- Add a Composition.Builder because Composition now contains a few
  optional fields.

Also, allow isNoOp to default to false without the TODO, so that implementations
of isNoOp must opt-in to implementing the override in order to be considered for
skipping the effect (ex. for transcoding in Transformer).

Implement getMediaFormatInteger, a helper method simulating mediaformat.getInteger(name, defaultValue).

This reduces the API 29 restriction from MediaFormatUtil.getColorInfo to API 24, in
particular removing the method-based restriction to a constant-based restriction,
so that we can reduce usage of the API 29 class.

This also allows us to slightly simplify prior use-cases where we'd check
containsKey and getInteger to have a default value.

When clipping a MediaItem with start time > 0, the audio was ending
before the video. This is because:
- Audio timestamps are computed based on the sample sizes, with a start
  time set to streamOffsetUs (i.e. the streamStartPositionUs is not
  taken into account).
- The SamplePipeline was subtracting streamStartPositionUs from the
  timestamps before sending the samples to the muxer.
- As a result, the audio timestamps were shifted by
  streamStartPositionUs, while they should be shifter by streamOffsetUs.
