For now, the only extension function on the `Player` has been used in a Compose demo. It can be promoted to a proper module where in the future other extension functions will reside. Given that `Player` is in `androidx.media3.common`, the corresponding KTX library for it is `androidx.media3.common-ktx`
To start using the new `suspend fun listen`, one must add `androidx.media3:media3-common-ktx` as a Gradle dependency and `import androidx.media3.common.listen`

Given that `Player` interface is written in Java and is has a callback-based Listener interface, we need an adapter for the Kotlin-native world.
This change introduces a suspending function `listen` that creates a coroutine, in order to capture `Player.Events`.

According to b/292763081 the build failure
`unresolved reference: addLast` in the session-demo is caused
by a bug in the Kotlin compiler 1.9.0 to which we depend.
Bumping the Kotlin plugin version to 1.9.10 which is the next
above 1.9.0 as listed in [1], the build problem is resolved.
Further, the Kotlin extension compiler version is set to 1.5.3
to make compose work with Kotlin 1.9.10 (see [2] for the
Kotlin/Compose compatibility map).

-----
Context:
* Each sequence is wrapped as a single MediaSource, each being played
by an underlying ExoPlayer.
* Repeat mode is typically implemented in Players as a seek to the next
item in the playlist.
-----
This CL:
Repeat mode is triggered by listening for when the main input player
sees a play when ready change due to the end of the media item.
There is a slight delay at the end of the playback, before it repeats.
Setting repeat mode on the underlying players addresses this, but means
that the players will seek without waiting for the CompositionPlayer,
and as such previewAudioPipeline does not get the correct signals
around blocking/flushing.
PreviewAudioPipeline - The seek position can validly be C.TIME_UNSET,
however preview pipeline did not handle this case.
CompositionPlayer getContentPosition is given (through a lambda) as a
supplier to the State object, which means any comparisons between
previous/new state for this value does not work. In SimpleBasePlayer,
there is logic to use the positionDiscontinuityPositionUs for the
position change (see getPositionInfo called from
updateStateAndInformListeners), however this logic is not considered in
getMediaItemTransitionReason, so a condition needed to be added for
this case.
-----
Tests:
* Dump files clearly show the position and data is repeated.
* Assertions on the reasons for transitions or position
discontinuities.

All other AndroidX libraries have already increased their min SDK to
21.
This change renames private symbols to remove `V21` suffixes and
similar, but doesn't change public or protected symbols with similar
names, to avoid needless breakages/churn on users of the library.
Some of the dead code removal is more complex, so I've split it out
into follow-up changes to make it easier to review.

The default value is 50 seconds.
Changed it to 5 seconds.
This prevents the player from buffering too much data and causing the app to crash due to OOM.
This was reported in https://github.com/androidx/media/issues/1506

The user might expect this button to back out to the configuration activity,
but actually it toggles pause/resume (though `cancel` is the method called).

This class is a lower-level UI component that isn't directly needed if
apps are using `PlayerView` to handle their video output (it is used as
an implementation detail of `PlayerView`).
Removing its unecessary usages from this demo avoids developers copying
this as an example when building their own apps.

Also move the track selection header strings to the demo app
as they are only used there (except for audio, which stays in UI)

This change adds `SessionError` and uses it in `SessionResult`
and `LibraryResult` to report errors to callers.
Constructors and factory method that used a simple `errorCode` to
construct error variants of `SessionResult` and `LibraryResult`
have been overloaded with a variant that uses a `SessionError`
instead. While these methods and constructors are supposed to be
deprecated, they aren't yet deprecated until the newly added
alternative is stabilized.

The nullness checking is very verbose and redundant in some places, for
example, the ensures-non-null marking in the transformer activity, and it makes
changing features in the demo app more time consuming. The cost/benefit balance
seems to be in favor of removing this for demo code.
Note: the ExoPlayer main demo has nullness checks turned off.

Underneath, it delegates to either
* `AndroidExternalSurface` (equivalent of SurfaceView), which is generally better for power and latency
* `AndroidEmbeddedExternalSurface` (equivalent of TextureView) which is better for interactions with other widgets or applying visual effects through the graphicsLayer
Note: the resulting surface is stretched across the whole screen. Aspect ratio handling will be addressed in the follow-up changes.

Add SeparableConvolution.configure(inputSize) to allow effect configuration
depending on input dimensions.
Add LanczosResample.scaleToFit method to scale input images to fit inside
given dimensions.

I originally tried switching to `Futures.addCallback` (as a follow-up
to Issue: androidx/media#890), but it seemed like a good chance to go further into
Kotlin-ification.
Before this change, if the connection to the session failed, the app
would hang at the 'waiting' screen with nothing logged (and the music
keeps playing). This behaviour is maintained with the `try/catch` around
the `.await()` call (with additional logging). Without this, the failed
connection causes the `PlayerActivity` to crash and the music in the
background stops. The `try/catch` is used to flag to developers who
might be using this app as an example that connecting to the session
may fail, and they may want to handle that.
This change also switches `this.controller` to be `lateinit` instead of
nullable.

This is generated in response to a deprecation warning in AS:
```
The option setting 'android.defaults.buildfeatures.buildconfig=true' is deprecated.
The current default is 'false'.
It will be removed in version 9.0 of the Android Gradle plugin.
You can resolve this warning in Android Studio via `Refactor` > `Migrate BuildConfig to Gradle Build Files`

This was previously only set on images because it was not ignored on
other media types. This parameter was made no-op for non-images in

For each item, AudioGraphInput now pads the input audio track with silence
to the duration given in onMediaItemChanged.
Possibly resolves Issue: androidx/media#921 .

This class is not ready for production app usage yet, so it is still
marked `@RestrictTo(LIBRARY_GROUP)` for now. Apps can experiment with it
in a non-prod context by suppressing the associated lint error.
* Issue: androidx/media#1014
* Issue: androidx/media#1185
* Issue: androidx/media#816

This annotation is only needed on public classes that are part of a
distributed library.
Switch to `@OptIn` for the one file where `@UnstableApi` was
suppressing lint errors.

* Consistently use 'playlist' instead of 'play list'
* Remove wording about 'playlist loading' since when this message is
shown the music is already playing in the background, we're just
waiting for the in-app controller to connect to the background
service.
