The native GL errors are in an arbitrary order according to
https://www.khronos.org/registry/OpenGL-Refpages/es2.0/xhtml/glGetError.xml
This means any of them could contain the most useful message
so it's better to use all for the GlException's message rather than
picking the last message and logging all others.

`codecDrainAction` is set to `DRAIN_ACTION_NONE` in 3 places in
`MediaCodecRenderer`:
* The constructor (so there's no prior state to worry about)
* `updateDrmSessionV23()`: Where `mediaCrypto` is reconfigured based
  on `sourceDrmSession` and `codecDrmSession` is also updated to
  `sourceDrmSession`.
* `resetCodecStateForFlush()`: Where (before this change) the action
  is unconditionally set back to `DRAIN_ACTION_NONE` and so any
  required updated implied by
  `DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` is not done.

This change ensures that `flushOrReleaseCodec()` handles
`DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` before calling .

Based on
https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface,
frame dropping behaviour depends on the target SDK version.
After this change transformer will only use
MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK
version are at least 29 and default to its pre 29 behaviour where each
decoder output frame must be processed before a new one is rendered
to prevent frame dropping otherwise.

Also remove deprecated Transformer.Builder constructor without a
context and the context setter.

Transformer always enabled glAssertionsEnabled, so there should
be no functional change.

ExoPlayer previously disabled glAssertionsEnabled, so GlUtil logged
GlExceptions instead of throwing them. The GlExceptions are now
caught and logged by the callers so that there should also be no
functional change overall.

This change also replaces EGLSurfaceTexture#GlException with
GlUtil#GlException.

The track selector will select multi-channel formats when those can be
spatialized, otherwise the selector will prefer stereo/mono audio
tracks. When the device supports audio spatialization (Android 12L+),
the DefaultTrackSelector will monitor for changes in the platform
Spatializer and trigger a new track selection upon a
Spatializer change event.

Devices with a `television` UI mode are excluded from audio channel
count constraints.

This change fixes a bug where the player is frozen with HLS chunkless
preparation because the audio stream wrappers are not marked as master
timestamp sources before preparation.

The service handles three different types of `Intents`. Custom command and media
command Intents created by the library and media button event Intents from other
sources.

Media commands from the library as well as from external sources have the action
set to `android.intent.action.MEDIA_BUTTON`. If the data URI is set and can be
used to identify a session then it is a library Intent. If the Intent is coming
from an external KeyEvent, the service implementation is asked which session to use
by calling `onGetSession(controllerInfo)` with the controller info being an
anonymous legacy controller info.

Intents representing a custom command are always coming from the library and hence
always have a data URI.

Some Player implementations have no playlist capability but can still
set a MediaItem for playback. Examples are a MediaController connected
to a legacy MediaSession, ExoPlayer up to 2.12 or MediaPlayer.

To indicate this capability, we need an allowed command in addition
to COMMAND_CHANGE_MEDIA_ITEMS that just allows to set a single item
that replaces everything that is currently played.

Use Collections.synchronizedSet() instead of creating a set from a
ConcurrentHashMap because ConcurrentHashMap has a bug in APIs 21/22
that can result in lost updates.

This removes the prior restriction of needing to remember not to crop and set aspect ratio in the same Presentation.Builder, and makes each class a bit more targeted.

This is partially made feasible by the past work to merge consecutive
MatrixTransformations into a single MatrixTransformationFrameProcessor, which
ensures that there's no loss in quality between successive MatrixTransformations.

With HLS chunkless preparation, audio formats may have no value
for channel count. In this case, the DefaultAudioSink will either query
the platform for a supported channel count (API 29+) or assume a max
channel count based on the encoding spec in order to decide whether the
audio format can be played with audio passthrough.

SingleFrameGlTextureProcessor is now an abstract class containing a
default implementation of the more flexible GlTextureProcessor interface
while still exposing the same simple abstract methods for single frame
processing it previously did.

FrameProcessorChain and GlEffect will be changed to use
GlTextureProcessor in follow-ups.

These legacy callbacks are currently forwarded to onSetMediaUri which
will be removed in the future.

Also make sure to only call player.prepare/play after the items have
been set.

The calls to onAddQueueItem are also forwarded to onAddMediaItems to
actually allow a session to resolve these items to playable media, which
wasn't possible so far.

The current setup with distinct, private `keyForField` implementations,
leaves open the (theoretical) possibility of a clash in the `Bundle`
keys used by the superclass and subclass. This change brings
consistency with our only other extensible `Bundleable` type
(`PlaybackException`).

We generally nest the `Builder` for `Foo` inside `Foo`. In this case,
there's already a `DefaultTrackSelector.Parameters.Builder` type visible
to a developer, it just happens to be the 'common'
`TrackSelectorParameters.Builder`, so using it is a bit weird. For
example this code snippet doesn't compile because
`DefaultTrackSelector.Parameters.Builder#build()` returns
`TrackSelectionParameters`. This CL fixes that problem and the code
snippet now compiles.

```java
DefaultTrackSelector.Parameters params =
   new DefaultTrackSelector.Parameters.Builder(context).build()
```

Implementations of this interface will be able to drop or add frames,
change timestamps, accept multiple input frames before producing
output, and process frames on their own background thread.

A default implementation of this interface will be added to SingleFrameGlTextureProcessor in a follow-up.

This is done by removing the `@FieldNumber` IntDef completely. It's not
really adding much value anyway, because it's `open` so there's no real
enforcement to prevent passing 'incorrect' values.

This internal listener avoids wrapping the TransformationExceptions
in PlaybackExceptions that are handled via the Player.Listener and
is also used for FrameProcessingExceptions which already avoided
the PlaybackException layer previously.

This listener will also be useful in follow-ups for encoder-related
TransformationExceptions that are thrown in the SurfaceProvider that
will be called on the GL thread.

Once the more advanced GlTextureProcessor interface exists,
it will be possible to change the output size of a GlTextureProcessor
between frames. To keep the re-configuration based on the frame sizes
minimal, things indepedent of the frame size, such as the GlProgram,
can be initialized in the constructor.
