Mentioning the realtionship on every other callback makes
it easier for the casual developer to understand the
relationship between the methods and discover the existence
of onEvents.

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.

This callback allows listeners to know when all simultanous changes
have been handled and the values reported through callbacks are
again completely consistent with value obtained from Player
getter calls.

When a stream has duplicate timestamps we currently discard to
the last sample with the specified discardTo timestamp, but
it should be the first one to adhere to the method doc and the
intended usage.

Background:
1. When the player has multiple audio renderers, by default they share a
single AudioSink.
2. When any new renderer is enabled, all disabled renderers are reset
prior to the new renderer being enabled. This is to give them a chance
to free up resources in case the renderer being enabled needs them. These
reset calls are expected to be no-ops for renderers that have never been
enabled.
The issue:
The problematic case arises when there are two audio renderers and a third
renderer (e.g., text) is being enabled. In this case, the disabled audio
renderer's reset call ends up resetting the AudioSink that's shared with the
enabled audio renderer. The enabled audio renderer is then unable to make
progress, causing playback to freeze.
This is a minimal fix that directly prevents the mentioned issue. There are
multiple follow-ups that would probably make sense:
1. Having ExoPlayerImplInternal track which renderers need to be reset, and
only resetting those renderers rather than all that are disabled. This
seems like a good thing to do regardless, rather than relying on those
calls being no-ops.
2. If we want to continue sharing AudioSink, we need to formalize this much
better and make sure we have good test coverage. Messages like
MSG_SET_VOLUME are also delivered to the AudioSink multiple times via
each of the renderers, which works currently because DefaultAudioSink
no-ops all but the first call in each case. This is pretty fragile though!

This only has a couple of simple tests for now. We'll add more tests
after we've written some concrete sub-class tests for various
DataSource implementations.
I've included a concrete FileDataSourceContractTest as a demonstration.

This ensures the buffer is not full when the `DefaultLoadControl` determines
whether we should continue loading and thus prevents a false warning about
not having enough memory left.

Add experimental method to synchronize MediaCodec interactions
with asynchronous queueing. When the feature is enabled, interactions
such as MediaCodec.setOutputSurface() triggered by the
MediaCodecRenderer will wait until all input buffers pending queueing
are first submitted to the MediaCodec.

To check what is safely possible we keep track of the live offset
corresponding to the buffered duration and only deecrease the
target offset to a safe margin from the buffered duration.
Also, while still possible (i.e. while the actual offset is larger
than the safe margin), we increase the target offset to the safe
margin to avoid rebuffers to start with.

Add more MediaCodec methods to MediaCodedAdapter so that renderers
interact with the MediaCodec through the MediaCodecAdapter.

- This change removes the last piece of logic that could cause deferred
codec release (i.e., where the decision to release was made in
processEndOfStream rather than in onInputFormatChanged.
- After this change, whether the codec will be released as a result of
a format change is always established in onInputFormatChanged.
