Estimating the playback frame-rate, querying the display refresh rate, and
setting the surface frame-rate, are all closely related to one another. In
particular because setting the surface frame-rate can directly cause the
display refresh rate to change. It therefore makes sense to move surface
frame-rate adjustment into the helper.
This also makes it easier to re-use the logic in other video renderers.

This replaces all the duplicated logic previously implemented in
FakeSampleStream and more closely follows the pattern of how
SampleStreams are used from real MediaPeriods.
Some tests needed adjustments because using real the SampleQueue
improved behaviour:
- Waiting for isLoading is only needed once even across period
boundaries because the real SampleQueue doesn't have the on/off
pattern.
- AnalyticsCollectorTest.playlistOperations() was wrongly asserting
that some pre-buffering events. The new version is more intuitively
correct we pre-buffer the second item during the initial loading
phase (thus period1seq1) and keep the buffer in the queue after
the removal operation.

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.

The adaptive period currently extends the base (non-adaptive) period
to share common MediaPeriod boilerplate code.
However, once we start using the real SampleQueue in FakeMediaPeriod
the common code becomes even less and the overhead to support
multiple stream implementation from the base class is no longer
worth it. Thus, this change removes the class hierarchy and copies
the common parts to FakeAdaptiveMediaPeriod.

This was added due to a misunderstanding - we're more interested in
testing the edge case of trying to read the last zero bytes of a
non-zero-byte resource.
In a future change I want to be able test reading a subrange, so each
TestResource will need to be at least N bytes long.

PlaybackStatsListener has a method whose original intention was to be
called when the player is releaed to finish all pending sessions.
However, this also meant that later events (e.g. onVideoDecoderDisabled)
could create new sessions because the old one was already finished.
Use the new onPlayerReleased callback to implement this properly and to
fix the unintentional new session creation.

Previously the `AdTagLoader` only had one listener which meant that updates
that should affect all periods with matching identifiers in the timeline only
affected the last-attached one. Fix this by having `AdTagLoader` track all its
listeners.

Currently we don't remove the AnalyticsListeners registed to
SimpleExoPlayer after calling release. We didn't do this mainly
because there are messages triggered as part of the release that
still cause interesting events (e.g. decoderDisabled with the
final counters, final dropped counts etc).
However, we should fully release/remove the listeners once these
pending events are delivered to:
1. Not leak listener implementations (e.g. if the listener is an
Activity)
2. Ensure we don't send future events that may cause listeners
to unintentionally access released or nulled variables. This
could happen for example if someone calls a player method
after the player was released.
In addition, we can add a onPlayerReleased callback to
AnalyticsListener to allow implementations to clean themselves up
once all pending events are delivered.

Fixed the verticalAnchorType and horizontalAnchorType calculation
The anchorID 0, 1 and 2 should correspond to verticalAnchorType=ANCHOR_TYPE_START, anchorID 3, 4, 5 is ANCHOR_TYPE_MIDDLE, anchorID 6, 7 and 8 is ANCHOR_TYPE_END
The anchorID 0, 3 and 6 should correspond to horizzonatlAnchor=ANCHOR_TYPE_START, anchorID 1, 4, 7 is ANCHOR_TYPE_MIDDLE, anchorID 2, 5 and 8 is ANCHOR_TYPE_END
When a listener is removed or released we may not have called
onEvents for events that happened before this point. To ensure
listeners don't miss events we need to trigger a final onEvents
with all events we have happened so far (if any).

This will allow Player to move in common without
trackSelector and all its many dependency.
Currently all users of `getTrackSelector` are
downcasting it in `DefaultTrackSelector`, this change
thus does not break them.
Track selection API is intended to be reworked, methods
will be added to the currently empty interface.

The old tag reflects the original name of this class. It was renamed in
2017:
<unknown commit>
Possibly the old name was kept for compatibility with existing logs
analysis? I didn't see an explicit discussion of this in the review
comments of the rename change.
The current tag confused me slightly - I assumed a line was being
emitted by the android.media.AudioTrack rather than ExoPlayer's
DefaultAudioSink.

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.

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.

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.

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.

Previously the PlaybackStatsListener needed to handle all events
individually, which required to keep some state of the player and
to resolve potentially transient state changes.
Using onEvents allows to channel all simultanous updates through
one method so that no transient player state and other
inconsistencies need to be handled. This makes the logic easier
to read.
In addition it also allows to resolve all simultaneous events to
use one EventTime (with one timestamp).

In many cases it doesn't matter for the test itself how many windows
a timeline has, or even how the timeline of a MediaSource looks like.
And since we introduced the MediaItem-based APIs, single-window
Timelines are the only fully supported Timelines. Thus there is no
point in specifiying this explicitly.
Using these assumptions, we can remove some boilerplate when setting
up standard FakeTimelines or FakeMediaSources with a standard
FakeTimeline.

The current code creates placeholder metadata elements if there is no
static metadata. This causes onStaticMetadataChanged callbacks even
if there is no metadata.
Instead, we can keep the empty list as the static metadata is already
documented to be an empty list if the metadata is unavailable.

The EventTime wasn't part of the onEvents callbacks so far because the
individual events may have different event times (e.g. if they relate to
different media periods). By adding a query method to obtain the
EventTime by event type, we can solve this issue.

Previously, VideoFrameReleaseTimeHelper didn't receive PTS values for
frames that were skipped. This would lead to unnecessary sync loss when
encountering such buffers, because the helper would see a frame-rate
change (i.e., the next frame being significantly longer than previous
ones). After this change, VideoFrameReleaseTimeHelper is notified of
all frame PTS values, so it can retain sync in this case.
This change also propagates onStarted and onPositionReset to the helper.
This paves the way for decoupling frame-rate estimation from release
adjustment sync. Note that currently, loss of sync effectively resets
both. This is unnecessary. For example, if the renderer is paused and
later resumed, then release adjustment sync needs to be reset, but any
frame-rate estimate we have is still valid.

RunnableFutureTask is not reusable. Trying to reuse it meant that a
failure in one doWork() call would cause subsequent download() calls
to (a) not block until the runnable has finished executing (does not
apply when using a direct executor), and (b) throw the same failure
as thrown from the first doWork() call.
This could cause #8078 if the initial failure occurred before the
content length was resolved. Retries are not blocked on their work
completing due to (a), and the download would be marked as failed due
to (b). The work itself could then resolve the content length, which
causes the stack trace in this issue.
