This is a candidate fix for #8906. As mentioned in that issue,
negative positions within windows might be (kind of) valid in
live streaming scenarios, where the window starts at some
non-zero position within the period. However, negative positions
within periods are definitely not valid. Neither are positions
that exceed the period duration.
There was already logic in ExoPlayerImplInternal to prevent a
resolved seek position from exceeding the period duration. This
fix adds the equivalent constraint for the start of the period.
It also moves the application of the constraints into Timeline.
This has the advantage that the constraints are applied as part
of state masking in ExoPlayerImpl.seekTo, removing any UI flicker
where the invalid seek position is temporarily visible.

Since playlist support was added, it's possible for the player to "have media"
and be in STATE_IDLE. The STATE_IDLE documentation therefore became incorrect.

This cl doesn't implement completely the API for
`ExoPlayerImpl` as
`onTrackSelectionParametersChanged` is not called.
The follow up cl adds `TrackSelectionParameters` in PlaybackInfo
to correctly propagate the change event and mask it.
Additionally `TrackSelectionParameters` is serialized as a Parcelable
for now. It is transitioned to bundleable in a follow up cl.

StyledPlayerControlView was checking whether the player is an ExoPlayer
instance to set the track selector. This means that, if apps were
wrapping an ExoPlayer in a ForwardingPlayer (to replace a
ControlDispatcher for example), the track selector wasn't set anymore.

Samples are serialized using our custom CueEncoder. Information in
which format samples are encoded is needed by Renderer to decide which
decoder to use. Extractor receives Format object in the constructor and
prepares new Format object with sampleMimeType moved to codecs field
and new sampleMimeType set to "custom serialized exoplayer Cue".

Most of those objects needs to be sent to MediaControler.
`TrackSelectior.Parameters` could have stayed Parcelable,
but it needs to be `Bundleable` as it inherit from
`TrackSelectionParameters` that is and needs to be
serializable anyway for the demo app.
As a result it has also been migrated to bundleable.

Adding a CHANGE_FRAME_RATE_STRATEGY_ALWAYS strategy is
omitted from this commit, since adding it is more complicated
than just plumbing it through and leaving everything else
unchanged. Specifically, VideoFrameReleaseTimeHelper would
need updating to behave differently when such a strategy is
enabled. It currently calls setFrameRate in cases such as
pausing, seeking and re-buffering, on the assumption that
changes to the underlying display refresh rate will only be
made if they can be done seamlessly. For a mode in which
this will not be the case, it makes more sense to stick to
the content frame-rate when these events occur. It may also
make sense to only use explicit content frame-rate values,
and not those inferred from individual frame timestamps.
Finally, for adaptive content containing a mix of frame-rates,
it makes sense to use the maximal frame-rate across all
variants, and to avoid calling setFrameRate on switches from
one variant to another.
Applications that know the frame-rate of their content can
set ExoPlayer's strategy to CHANGE_FRAME_RATE_STRATEGY_OFF and
then use setFrameRate directly on the output surface. Note that
this is likely to be a better option for apps than anything we
could implement in ExoPlayer, because the application layer
most likely knows the frame-rate of the content earlier than
ExoPlayer does (e.g., to perform the disruptive mode switch
at the same time as an activity transition).
Adding CHANGE_FRAME_RATE_STRATEGY_ALWAYS will be deferred
until there's clear demand for it. In the meantime, we'll
recommend the alternative approach above.

This CL introduces two classes:
* CueEncoder - encodes list of Cue object into byte array.
* CueDecoder - decodes byte array into list of Cue objects.
This two classes are necessary in order to push Cues through SampleQueue. This classes are meant to be used by subtitle Extractor.

The AnalyticsCollector releases listeners lazily so that listener
callbacks triggered on the application looper after
SimpleExoPlayer.release() are still handled. The change in ListenerSet
to post the onEvents callback on the front of the application looper
changed (correctly) how onEvents are propagated, however this made
the AnalyticsCollector deliver onEvents with out-of-order EventTimes.
This change fixes AnalyticsCollector to trigger onPlayerReleased() and
the matching onEvents() event in the correct order.

- Use timestampOffsetUs == C.TIME_UNSET directly as the way of
determining whether the adjuster has determined the offset,
rather than relying on lastSampleTimestampUs checks for this.
- Remove comment referring to lastSampleTimestampUs as holding
the "adjusted PTS". Its value may not have originated from a PTS
timestamp. It's also confusing to refer to it as "adjusted"
given timestampOffsetUs has not been applied to it.
- Fix PassthroughSectionPayloadReader to make sure it'll never
output a sample with an unset timestamp.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.
Notable renamings that might be controversial:
- `onPlaybackStateChanged(int state)` to `onPlaybackStateChanged(int playbackState)` affected a lot of lines but seems more consistent with other '-Changed' methods.
- `handleMessage(int messageType, Object payload)` to `handleMessage(int messageType, Object message)`
- `ExtractorInput` and `DataSource` inherit `DataReader` which had `read(byte[] target, ...`, while data sources normally called the first parameter `buffer`. I have standardized these all to use `buffer` even though it looks out of place in the `ExtractorInput` interface (which has more `read` methods with `target`).

The documentation on ByteArrayOutputStream and GZIPOutputStream isn't

AssertionError seems a bit strong - but it seems very unlikely, so we

The inference is used when nesting DataSourceExceptions. It is removed because
nesting does not add additional value in surfacing the exceptions, and it is
better to assign an error code at the throw site (in the "leaf" or the bottom
most data source).
PiperOrigin-RevId: 386919118
In some DataSources, it is not easy to assign an error code at the throw site.
For example, CronetDataSource.readInternal() throws SocketTimeoutException
on L1033, and is caught at L754 as IOException and is thrown.
We need the logic to assign error code for the actual type of the error cause.
While we can certainly do in individual DataSources, IMO there's value in
making this logic generic at a higher level (like what is in this CL).
The catch and translation logic is borrowed from EPII:L646.

Applications may need to pass a non-visual context when creating
a DefaultTrackSelector (e.g., because they're audio-only or are
creating the selector in a background service).
Obtaining the default display via DisplayManager avoids the strict
mode violation that occurs when retrieving it via WindowManager.

Most of the super-interfaces are deprecated, but the intention is that
only the types are deprecated and the methods themselves shouldn't be.
In order to reflect this in javadoc we override all the methods in
`Player.Listener` in order to 'cancel' the deprecation.
This change deliberately doesn't override methods that are explicitly
deprecated with documented replacements (like
`Player.EventListener#onPlayerStateChanged`) - these should contine to
be marked as deprecated in javadoc.

The parameters staying in DefaultTrackSelector are considered
too ExoPlayer specific to be part of the `Player` interface.
Those are:
- exceedVideoConstraintsIfNecessary;
- allowVideoMixedMimeTypeAdaptiveness;
- allowVideoNonSeamlessAdaptiveness;
- exceedAudioConstraintsIfNecessary;
- allowAudioMixedMimeTypeAdaptiveness;
- allowAudioMixedSampleRateAdaptiveness;
- allowAudioMixedChannelCountAdaptiveness;
- disabledTextTrackSelectionFlags;
- exceedRendererCapabilitiesIfNecessary;
- tunnelingEnabled;
- allowMultipleAdaptiveSelections;
- rendererDisabledFlags
Track selection override will be migrated in a follow up cl.
To avoid breaking backward compatibility,
`DefaultTrackSelector.Parameters` extends
`TrackSelectionParameters` and
`DefaultTrackSelector.ParametersBuilder` extends `TrackSelectionParameters.Builder`.
The change are thus transparent for clients.
Test are incomplete for now, as this is a relatively big cl, I though
the reviewer could give a first pass will the tests are completed.
