Our FakeClock generally makes sure that playback tests are fully
deterministic. However, this fails if the test uses blocking waits
with clock.onThreadBlocked and where relevant Handlers are created
without using the clock.
To fix the flakiness, we can make the following adjustments:
- Use TestExoPlayerBuilder instead of legacy ExoPlayerTestRunner
to avoid onThreadBlocked calls. This also makes the tests more
readable.
- Use clock to create Handler for FakeVideoRenderer and
FakeAudioRenderer. Ideally, this should be passed through
RenderersFactory, but it's too disruptive given this is a
public API.
- Use clock for MediaSourceList and MediaPeriodQueue update
handler.

I considered moving this enforcement inside the ExoPlayerImpl
implementation, but it might lead to app crashes in cases that apps
(incorrectly) call a released player, but it wasn't actually causing a
problem.

1. The offloadSchedulingEnabled value doesn't need to be in
PlaybackInfo because it's never updated in EPII.
2. The sleepingForOffload value in EPII wasn't updated explicitly
(just via the return value of a method). It was also only
meant to be enabled while the player is actively playing, but
confusingly triggered from a path where the player may
theoretically be buffering as well.
3. The offload sleeping (=not scheduling doSomeWork) was interwoven
into the actual scheduling code making it slightly hard to follow.
This can be improved slightly by keeping the offload sleeping
decision and the scheduling separate.

Refactor the overall module to place the unified vorbis tags into a
single package called `vorbis`. Also re-intoduce the vorbis tags
in their original `flac` module, but deprecate them.
Where this introduced an inconsistency (e.g. assigning to something
called `windowIndex`), I generally renamed the transitive closure of
identifiers to maintain consistency (meaning this change is quite
large). The exception is code that interacts with Timeline and Window
directly, where sometimes I kept the 'window' nomenclature.

Enable subtitle output in the PlaybackOutput and disable the text
renderer in the MkvPlaybackTest. Add WebvttPlaybackTest to test the
output of side-loaded WebVTT subtitles.

Those test are no longer flaky since the test clock
was made deterministic.
The removed assertions were introduced in a4ad351fb1.

All `add*Listener` and `add*Output` methods are
deprecated in favor of `addListener`.
As for the class themselves `VideoListener` and
`AudioListener` are not used internaly by ExoPlayer,
`VideoRendererEventListener`
and `AudioRendererEventListener` are use in their
place.
As a result `VideoListener` and `AudioListener`
can be deprecated in favor `Listener`.
On the other hand `TextOutput` and `MedataOutput`
are used both in the player interface and internally in
renderers.
This means that those class can't be deprecated.
There usage in the public interface are indirectly
deprecated as their is no way to use them without
using the deprecated `add*Output`.
Thus it's not an issue that the class themselves are
not deprecated.

Add additional assertions to try to figure out why
the tests are flaky when run in the test harness.
Failure could not be reproduced locally even after 4000 run.

This is achieved by only triggering one message at a time. After
triggering a message we send another to ourselves to know when the
following message can be triggered.
Other required changes:
- The messages need to be sorted correctly (by time and creation order)
- To prevent deadlocks when one thread is waiting for another,
we need to add new method to Clock to indicate that the current
thread is about to wait. This then allows us to trigger messages
from other threads in FakeClock.
- AnalyticsCollectorTest needed some adjustments:
- onTimelineChanged now deterministically arrives after the initial
timline is already known, so some of the period information changes
from window only to full period info.
- The playlistOperations test suffers from a bug that the first frame
is rendered too early and that's why we now get additional events.

This is needed for the MediaFormat#getInteger calls in onConfigured().
The end-to-end playback tests this is used for have to run on API 29
anyway (because of ShadowMediaCodec and ShadowMediaCodecList
functionality).

This ensures the message devilery is governed by the clock.
Also replace setting a Handler with a Looper to facilititate this
change.

The output dumps are intentionally empty because the playback
is using bypass modes.
Still adding a AUDIO_RAW decoder to the ShadowMediaCodecConfig to
ensure that we would output samples if bypass mode were disabled.

The cache, being static, is updated every time a new MimeType is encountered.
The static cache needs to be cleared between tests that register codecs through
ShadowMediaCodec, or the subsequent tests could possibly pick up a wrong codec.

I decided not to migrate all the tests in one CL to keep the diff
manageable. I'll make follow-up CLs to migrate the tests, and eventually
delete TeeCodec and all associated logic.
I couldn't completely remove the dump diff because
ShadowMediaCodec.getCodecInfo() (which would give me access to the MIME
type) doesn't seem to work properly - it returned video/avc when
name=exotest.audio.aac, and looking into the code it looks like there's
some native methods that are missing shadow implementations.
