This is equivalent to the existing `scaleLargeTimestamp` method with the
following changes/improvements:
* No longer specific to timestamps (there was nothing inherently
time-specific about the logic in `scaleLargeTimestamp`, but the name
and docs suggested it shouldn't be used for non-timestamp use-cases).
* Additional 'perfect division' checks between `value` and `divisor`.
* The caller can now provide a `RoundingMode`.
* Robust against `multiplier == 0`.
* Some extra branches before falling through to (potentially lossy)
floating-point math, including trying to simplify the fraction with
greatest common divisor to reduce the chance of overflowing `long`.
This was discussed during review of 6e91f0d4c5
This change also includes some golden test file updates - these
represent a bug fix where floating-point maths had previously resulted
in a timestamp being incorrectly rounded down to the previous
microsecond. These changes are due to the 'some more branches' mentioned
above.

Created new method `AudioSink#setOffloadDelayPadding` that will set delay and padding data onto an `AudioTrack` using `AudioTrack#setOffloadDelayPadding`. This feature adds support for offloaded, gapless Opus playback as the content requires the capability to set padding data post-`AudioSink#configure`.

In most cases, the places that were trying to avoid a transitive
dependency on `lib-exoplayer` when this duplication was introduced [1]
are already depending on it again, except for `lib-container` where the
dep is added in this change.
In general it seems fine for the tests of module A to depend
(transitively or directly) on module B even where the prod code of
module A **does not** depend on module B.

In an upcoming change I'm going to mark SSA subtitles as 'merge
replacement behavior', which will mean that
`CuesWithTiming.durationUs=C.TIME_UNSET` will not be permitted. This CL

This `DvbParser` was updated to implement the new `SubtitleParser`
interface in 2261756d3a.
This method used to return a `List<Cue>`, but now it returns a
`List<CuesWithTiming>`, which is closer to `List<List<Cue>>`. The
previous method returned an empty list, meaning a single 'event' with
no cues. After the change above the method still returns an empty list,
but that now means 'no events'. In order to maintain the old behaviour,
this change updates it to return a single-item list containing an empty
list of cues.

`SubtitleExtractor` used to rely on a `SubtitleDecoder`. However, now all SubtitleDecoders that are used for side-loaded subtitles have been migrated to a `SubtitleParser` interface. We can therefore refactor the extractor.
The `SubtitleExtractor` is only used for side-loaded subtitles which means we do not require the migration of the CEA-608/708 `SubtitleDecoders`.

Instead of `text/x-exoplayer-cues`, we will use `application/x-media3-cues`.
The prefix should be `application` not `text` since the encoded form is arbitrary bytes, not necessarily text. The name should not reference `exoplayer`, since the Media3 Extractors (which are not part of `exoplayer`) produce this format.

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

It is not part of the `SubtitleParser` interface's promise to give events for all changes to do with `Cue` objects. So while in the past, we would have `endTimeUs` of one Cue event being the `startTimeUs` of the next one, now we have that encoded in `durationUs` and can skip event with empty `Cues`.

PiperOrigin-RevId: 549298733
The end-to-end test output for the overlapping SRT and SSA subtitles
is currently incorrect. They will be fixed in a future change that
updates `TextRenderer` to support this overlap.
The 'extra' samples visible in the extractor test output files are
'empty cue list' samples produced by `SsaParser`. They will go away
when this implementation is updated to remove this behaviour and rely
on `CuesWithTiming.durationUs` instead (the 'empty list' behaviour is
not required by the `SubtitleParser` interface).
PiperOrigin-RevId: 549264593
This fixes two things in one go:
1. In order to indicate 'end of a cue' **without** relying on
`CuesWithTiming.durationUs`, `SubripParser` should have been emitting
an empty `List<Cue>` instead of the current behaviour of a
single-item list with `cue.text=""`.
2. There's no need for the empty cue (or cue list), we can use
`durationUs` to indicate the end of each list of cues.
There's no real need to ever have a `Cue` with `text=""`, so also
deprecate `Cue.EMPTY`.

This is a step towards adding general support for overlapping
subtitles in these formats (and others), both muxed and sideloaded:
* Issue: google/ExoPlayer#10295
* Issue: google/ExoPlayer#4794
This change adds these files to the end-to-end playback tests too, but
the subtitle track is currently disabled because renderer-side subtitle
parsing causes flaky tests (due to an uncontrolled thread in
`SimpleSubtitleDecoder`). The subtitle track will be re-enabled in
a follow-up change when loading-side subtitle parsing is added (so the
tests will no longer be flaky). At this point the overlapping subtitles
**still** won't be supported end-to-end, but a second change will
resolve this will changes in `TextRenderer` - which will change the
end-to-end playback dumps to reflect the overlapping subtitles.

`DvbDecoder` which used to be `SimpleSubtitleDecoder` will now be called `DvbParser` and implement `SubtitleParser` interface. There was, however, already a `DvbParser`, used by `DvbDecoder` behind the scenes. Hence, the refactoring only requires the existing `DvbParser` to adhere to the new `SubtitleParser` interface.

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`).

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first

samples are they have an inherent duration and trimming them this
way is not possible.

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).

These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)

This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.
The `isMiscCode` method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.
