`SubripDecoder` which used to be `SimpleSubtitleDecoder` will now be called `SubripParser` and implement `SubtitleParser` interface. For backwards compatibility, we will have the same functionality provided by `DelegatingSubtitleDecoder` backed-up by a new `SubripParser` instance.

`DelegatingSubtitleDecoder` is a `SimpleSubtitleDecoder` that delegates to a `SubtitleParser` instance (e.g. future implementations like `WebvttParser`, `SubripParser`, `SsaParser`, `DvbParser` etc)
It will be in the `exoplayer` package, rather than `extractor` and only be used in the decoding flow which happens after SampleQueue (and to be deprecated). When this decoding flow is deprecated and removed, the class can be later deleted.

This makes tests more realistic because the returned value matches
the rest of the simulated test time.
It also prevents test flakiness in (yet to be written) tests that
may not correctly advance the playback time in the position tracker.

When selecting progressive and HLS tracks, we currently check if
we can either seek in the existing samples or are starting from the
beginning of the stream. In both cases, we don't need to reload the
stream and can continue reading.
Seeking to the beginning isn't side-effect free though because it
also sets the startTimeUs to zero. Whether a seek to the beginning
is successful also depends on whether we already loaded a sample or
not. This mean that the startTimeUs value is set (or not set) based
on the speed of the Loader thread even for the same input starting
from the beginning. This race condition means the actual samples
we write to the stream may differ if the stream has initial samples
with negative timestamps.
We can avoid this race condition by checking if the queue is empty
first, so that we only call seekTo if really needed.

Robolectric writes warnings to the log output because the Surfaces
we create are not released and pollute the test environment. This
causes performance issues if tests are run repeatedly.
PiperOrigin-RevId: 545906757
We have the optimization to skip buffers if the release time is
exactly the same as the one for the previous buffer. This makes
sense under the assumption that these buffers get released to
a visible Surface and will be ignored anyway.
However, it's also helpful to provide a customization option to not
do this for cases where the outputting MediaCodecAdapter is not
directly talking to a visible Surface or for tests where we can't
fully control the vsync timing of the Surface and want to ensure
we output all samples that are meant to be shown.

This makes tests more realistic because the returned value matches

Upon track transition of offloaded playback of gapless tracks, the framework will reset the playback head position. The AudioTrackPositionTracker must be made to expect the reset and cache accumulated sum of rawPlaybackHeadPosition.

This allows MediaSources to accept MediaItem updates after creation.
This CL adds the handling and plumbing logic in `ExoPlayerImpl`,
`ExoPlayerImplInternal`, `MediaSourceList` and `MaskingMediaSource`.
It also updates all forwarding/wrapping sources to forward these calls
to their wrapped instance.
The actual functionality is only added to `FakeMediaSource` instances in
tests so far.

This plumbs a duration through `SampleQueue` which will make it easier
to handle transcoding muxed subtitles from e.g. SubRip to
`text/x-exoplayer-cues`.
This change is a no-op to the end-to-end behaviour of ExoPlayer because
currently we only support parsing sideloaded subtitles before
`SampleQueue`, and by adding the duration we don't affect the cues that
are ultimately output by `Player.Listener.onCues` (as shown by no change
to the golden files for `WebvttPlaybackTest` in this commit).
I considered making `CuesWithStartTimeAndDuration` implement
`Bundleable` (and deleting `CueEncoder/Decoder`) but decided against
it because we are deliberately not encoding `startTimeUs` (since that's
encoded as the sample time in `SampleQueue`). I also considered
introducing another type that only has `List<Cue>` and `durationUs`
fields, but it didn't seem necessary, since we want `startTimeUs`
everywhere else (except inside `SampleQueue`).

It currently wrongly documents that it is only called before reading
streams (that has never been the case and all MediaPeriods already need
to handle calls after reading samples from the streams).
It was also a bit unclear what a discontinuity implies and the new
Javadoc calls out the main use case for discontinuties and the intended
meaning of returning a discontinuity.

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

Mark output sample as decode-only based on start time
We currently do the same check on the input timestamps and
expect the output timestamps to match. Some codecs produce
samples with modified timestamps and the logic is a lot safer
when the comparison with the start time is done on the output
side of the codec.

This change uses this new method everywhere we currently `instanceof`
check an `Extractor` directly. This allows us to introduce
wrapping/delegating `Extractor` instances - because the `instanceof`
checks will continue to operate on the underlying instance.
HLS is a slightly different case, because it directly re-instantiates
`Extractor` instances, which is not compatible with an arbitrary
wrapping structure. Luckily the only `Extractor` instances that HLS
re-instantiates do not support muxed subtitles, so won't be wrapped
in the first place (although future changes might use the
delegating-`Extractor` pattern for other purposes, which might affect
HLS).

When an app tried to re-prepare a live streeam with server side inserted
ad after a playback exception, the player tried to find the ad group by
its index in the ad playback state of the next timeline when creating
the first period.
If a source that supports server side ad, has removed the ad playback
state when the source has been removed, this causes a crash. For live
streams this is a reasonable thing to do given the exception could be
caused by an invalid ad playback state.
This change removes the ad metadata from the current period for live
streams and the timeline. In case the ad playback state is not reset
by the source, the first timeline refresh would ad the metadata again.

Some events may arrive after the playlist is cleared (e.g. load
cancellation). In this case, the DefaultPlaybackSessionManager may
create a new session for the already removed item.
We already have checks in place that ignore events with old
windowSequenceNumbers, but these checks only work if the current
session is set (i.e. the playlist is non-empty). The fix is to add
the same check for empty playlists by keeping note of the last
removed window sequence number.

Instead of providing `playbackDurationUs` and `loadPositionUs` individually, which are used to calculate the buffer duration for CMCD logging, we can directly pass the pre-calculated `bufferedDurationUs` available in the `getNextChunk` method of the chunk source classes.

The existing NullableType has been deprecated 5 years ago and causes
crashes in Kotlin apps because Kotlin doesn't recognize this annotation
as a nullable type annotation.
While we can't align on a single @Nullable annotation yet, we can at
least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all
requirements, including full Kotlin compatiblity. To avoid the
cumbersome name, we can redefine it as our own @NullableType
annotation. (We can't use @Nullable to avoid name clashes with the main
@Nullable annotation from AndroidX)

Previously `AsynchronousMediaCodecCallback.mediaCodecException` was
cleared when flushing completed. This behaviour was changed in
aeff51c507
so now the exception is not cleared.
The result after that commit was that we would **only** suppress/ignore
the expression if a flush was currently pending, and we would throw it
both before and after the flush. This doesn't really make sense, so this
commit changes the behaviour to also throw the exception during the
flush.
This commit also corrects the assertion in
`flush_withPendingError_resetsError` and deflakes it so that it
consistently passes. The previous version of this test, although the
assertion was incorrect, would often pass because the
`dequeueInputBuffer` call would happen while the `flush` was still
pending, so the exception was suppressed.

With playback suppression in place, the devices can be added when the playback on ExoPlayer is in the suppression state. Also, it is quite possible that a suitable audio output device on which playback is ongoing gets removed requiring the Player to pause the playback. These requirements can be fullfilled using AudioDeviceCallbacks which has been implemented with this change.

Add support for including Common Media Client Data (CMCD) in the outgoing requests of adaptive streaming formats DASH, HLS, and SmoothStreaming.
API structure and API methods:
* CMCD logging is disabled by default, use `MediaSource.Factory.setCmcdConfigurationFactory(CmcdConfiguration.Factory cmcdConfigurationFactory)` to enable it.
* All keys are enabled by default, override `CmcdConfiguration.RequestConfig.isKeyAllowed(String key)` to filter out which keys are logged.
* Override `CmcdConfiguration.RequestConfig.getCustomData()` to enable custom key logging.
NOTE: Only the following fields have been implemented: `br`, `bl`, `cid`, `rtp`, and `sid`.
