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.

Prior to this change, an initalized TimestampAdjuster that's then
reset with DO_NOT_OFFSET would incorrectly continue to apply the
offset.
Also add a test case for this issue, and for some other simple use
cases.

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 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.

The types (open/close/read) does not provide extra information about the thrown
playback exception, and they are not utilized at higher levels.

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.

The serialization scheme used here is custom, it doesn't need
to be compatible with emsg-v0 or emsg-v1 (since
97183ef558).
This means that C.TIME_UNSET will propagate correctly through the
serialization.

- Use `PlaybackException.ErrorCode` IntDef for `DataSourceException` error code
- Deprecate `DataSourceException.POSITION_OUT_OF_RANGE`
- All other changes are related to replacing the deprecated constant and
constructor

Currently when a HTTP POST request receives a 302, CronetDataSource will change the request method from POST to GET for the redirected request, and drop the post body. This aligns with the behaviours of many user agents, but our use case would like to keep the POST method and the post body.
org.chromium.net.UrlRequest.followRedirect also changes POST to GET for 302, so should be avoided here.

This helps to remove old ad groups (e.g. those that fell out
of the live window) to keep the data size of AdPlaybackState small.
Also added this case to some existing unit tests to ensure it's
covered.
PiperOrigin-RevId: 376170653
This allows to decouple the data structure from the access. In
a future change, this allows to completely remove old ad groups
(e.g. for live streams where the number of groups would otherwise
grow forever).
Also move the time into the group itself for better encapsulation.

When working with SSAI ads, we need to easily convert positions between
the underlying stream and the media model that exposes ad groups. To
simplify this, we can add util methods (that are testable on their own).
In addition, we need an easy way to build AdPlaybackStates for SSAI
inserted ads. The metadata is obtained out-of-band and usually has the
ad group start and end times in the underlying stream only. Hence, we
also add a util method to add a new ad group based on this information.

Make ForwardingPlayer implement Player and not extend BasePlayer so that
ForwardingPlayer forwards each Player method directly to the wrapped
Player instance.
PiperOrigin-RevId: 374161084
There are two main changes that need to be made:
1. Whenever we determine the next ad to play, we need to select a
server-side inserted ad even if it has been played already (because
it's part of the stream).
2. When the Timeline is updated in the player, we need to avoid changes
that would unnecessarily reset the renderers. Whenever a Timeline
change replaces content with a server-side inserted ad at the same
position we can just keep the existing MediaPeriod and also if the
duration of the current MediaPeriod is reduced but it is followed by
a MediaPeriod in the same SSAI stream, we can don't need to reset
the renderers as we keep playing the same stream.
PiperOrigin-RevId: 373745031
Content after ad groups currently always resumes at the ad break position (unless
overridden by a seek or similar). In some cases, media inserting ads wants to
specify an offset after the ad group at which playback should resume. A common
example is a live stream that inserts an ad and then wants to continue streaming
at the current live edge.
Support this use case by allowing ad groups to specify a content resume offset
and making sure that the content start position after the ad group uses this offset.
