This is currently flaky, so it's better to disable it than end up with
flaky tests.

Migrate all classes that are simple to move to
common.

The `AudioProcessor` interface requires that no more input is queued after
queueing end of stream, but `DefaultAudioSink` did queue more input and the
implementation of `SonicAudioProcessor` actually relied on this to drain output
at the end of the stream.

Fix this behavior by getting `Sonic` output in `getOutput` and having
`DefaultAudioSink` only queue input to processors that are not draining.

Also add TODOs to clean up audio processor implementations where the code
handles interaction that doesn't conform to the interface.

As Player depends on VideoScalingMode, and
Renderer should not move to common,
to move Player to common, VideoScalingMode
needs to move first.

Changes MetadataRetriever and Transformer so that their
respective tests don't need to manually control the SystemClock
in order to execute taks posted with delay from Loader.

Low latency streams potentially need to remove preload chunks in case they are removed from the playlist. Hence we need to schedule loading the next playlist even if the playlist is not a primary playlist.

Previously `MediaPeriodQueue` would return null if an ad media URI hadn't
loaded yet, but this meant that the player could be stuck in `STATE_READY` if
an `AdsLoader` unexpectedly didn't provide an ad URI. Fix this behavior by
masking ad media periods. `MaskingMediaPeriod` no longer requires a
`MediaSource` to instantiate it.

This also fixes a specific case where playback gets stuck when using the IMA
extension with an empty ad where the IMA SDK unexpectedly doesn't notify the ad
group fetch error.

The inner class was only used to obtain 3 distinct pieces of
information which is better handled by static methods.

This method should be assumed to clear the data of the underlying array
(it will do this if the new limit > data.length).

This means it should only be called (directly) before writing into the
backing array.

It shouldn't be used as a shorthand for position=0, limit=x - those
should be two explicit method calls.

Most of these changes are no-ops, but they make the code more correct.

The TS SectionReader can't be easily changed to be 'safe', because it
relies on sectionData maintaining state between iterations of the while
loop. Instead I've added comments justifying the existing code.

The workaround to post a message was needed to ensure we
receive any final onIsPlayingChanged event before the test
is finished (to record the correct playing time).

Using onEvents allows us to do this synchronously as the
callback guarantees that there is no other pending event.

This ensures we have full test coverage for proguard configs now.
The only configs not covered by tests are:
 - IMA and OkHttp which copy recommended configs from the respective
   library. I couldn't reproduce failures by removing them (and thus
   couldn't write a test that ensures they are correct).
 - Some dontwarn lines that just suppress warnings.

In addition, this change fixes a couple of related issues:
 - Moved AV1 proguard config to correct module.
 - Removed mentioning of deprecated ExtractorMediaSource from README
 - Suppressed warning from IMA code that prevent proguarding under
   strict rules
 - Fixed wrong proguard exclusion in VP9 module.
 - Moved FLAC exclusion (DefaultExtractorsFactory) to correct module.
 - Added AlertDialog suppression for de-jetified code.
 - Removed unusued dependency from UI module that causes large APK
   size increase.

- Retire YouTube streams. They're flaky (e.g., one of them has transformed into
  an audio only stream!). There is also a desire for us to stop relying on special
  non-expiring YouTube URLs.
- Reorganize the remaining streams.
