This is more clear than using Format.NO_VALUE, when we do actually intend for an
output value.
Also, fix @see formatting by using summary fragments instead, and add an error
output for OETF and EOTF transfer functions.

This change includes a change in the `IMediaController.aidl` file and needs
to provide backwards compatibility for when a client connects that is of an older or
newer version of the current service implementation.
This CL proposes to create a new AIDL method `onPlayerInfoChangedWithExtensions`
that is easier to extend in the future because it does use an `Bundle` rather than
primitives. A `Bundle` can be changed in a backward/forwards compatible way
in case we need further changes.
The compatibility handling is provided in `MediaSessionStub` and `MediaControllerStub`. The approach is not based on specific AIDL/Binder features but implemented fully in application code.

If there is output data available (outputBuffer.hasRemaining()), then
there is no need to move other data between the underlying processors.
It will not change the buffer being returned by that call to getOutput.
If there is no output data readily available, it's necessary to go to
the AudioProcessors and pass buffers between them, as this may produce
data for output.

Previously, FrameProcessor never had the usecase in which the output surface
is replaced, while previewing introduced this usecase.
When switching output surfaces, we need to destroy the EGL Surface linked to the
surface that is being swapped out, because an EGL surface is linked to the EGL
display (which is not destroyed even when releasing FrameProcessor).
A GL exception will be thrown in the following scenario if we don't destroy the
EGL surface:
1. Creates a Surface, the surface is identified by address 0x11
2. Sets Surface(0x11) on FrameProcessor. Eventually an EGL surface is created
to wrap Surface(0x11)
3. Release FrameProcess, this releases the EGL context
4. Instantiate a new FrameProcessor, sets Surface(0x11) as the output
5. When FrameProcessor creates an EGL surface to wrap Surface(0x11), GL throws
an exception, becasue Surface(0x11) has previouly been connected to an EGL
surface.

Util.getAudioTrackChannelConfig() maps a channel count to a
channel mask that is passed to AudioTrack. The method expected that
playback of 8-channel audio is possible from Android 5.1 and playback of
12-channel audio is only possible from Android 12L. However, there is no
restriction on the upper number of channels that can be passed to the
AudioTrack. google/ExoPlayer#10701 is an example where the audio decoder
outputs 12 channels on an Android 10.
This change removes the restrictions for 8 and 12 channels. Note, we still
do not support playback of arbitrary number of channels as it would require
further changes to DefaultAudioSink.

When we currently trigger the iteration finished event during the
release, we don't mark the event as triggered. This means that
someone can trigger another release from within the callback,
which then tries to resend the event.

Make it easier to support use of RGBA_101012 rather than RGBA_8888 for EGL
contexts, displays, and surfaces.
This tangentially supports adding HDR tests, by slightly simplifying the color
selection logic we'd have to add in HDR tests.

Currently, repeating the same item (via seekNext/Previous) implicitly
results in a seek to the default position of the current item, which
looks exactly the same as a direct seek. As a result, we don't send
onMediaItemTransition as we would for every other seekNext/Previous
call.
This can be fixed by explicitly marking the repeat case in the internal
BasePlayer/ExoPlayerImpl methods, so that the callback can be triggered.

A follow up to stopping speaker playback with a Player decorator from
https://github.com/androidx/media/issues/15.
It looks like we will need to change to using playback suppression to avoid
errors like https://github.com/androidx/media/issues/167, when we don't start
a foreground service.
We may not have this implemented by 1.0, but would like it in the API and it seems to be appropriate.

* Before this CL, the texture was stored during the construction of the LUT processor. This failed since if one creates a list of GlEffects on the application thread, the texture will get stored in the application thread during the effect creation and not on the GL thread, which executes the FrameProcessors.
* This is an issue since the executing thread then can't index from the texture stored on a different thread.

The stream offset is used to calculate the presentation time of
a metadata object when reading and later when playing, to calculate
the current presentation time to decide whether to send the metadata
to the output.
Accordingly, the presentation time of a pending metadata that has been
calculated with a given offset needs to be recalculated when the
stream offset changes.

Use the PQ OETF and EOTF to ensure that intermediate fragment shader operations
using PQ are in linear BT.2020 rather than PQ and HLG-1 BT.2020.
Also, swap the OETF and EOTF in shaders, as they were used incorrectly before
Manually tested by verifying transformer demo HLG and PQ videos look the same with and without this CL, including with a BitmapOverlayProcessor enabled to test flows both with one MatrixTransformationProcessor that skips HDR TFs, and with one that doesn't.

We create an empty CueGroup in many places as default or

While HDR is most closely tied to the color transfer (ex.
COLOR_TRANSFER_SDR is the only one explicitly mentioning dynamic
range), technically color spaces may be associated with HDR as well,
like BT.2020 commonly being used for HDR rather than BT.709 for SDR.
Therefore, it's more specific to mention just that the transfer is HDR.

This allows the GlEffectsFrameProcessor to later handle HLG and PQ
differently, or limited and full color range differently.

Format.NO_VALUE is a placeholder value for an invalid @C.ColorTransfer, used
for example when the decoder doesn't support this transfer function.
When encountering this invalid value, interpret this as COLOR_TRANSFER_SDR.
Confirmed locally that an exception is thrown when transcoding on p4head, and no exception is thrown when transcoding with this CL.

This adds two methods that are helpful when working with Futures.
One is a version of postOrRun that can indicate completion by a
Future and the other is a simplified version of Guava's
Futures.transformAsync (which can't be used as it's in Beta).

This will help developers self-diagnose issues like Issue: google/ExoPlayer#10392
where the NPE occurs far from the original null value because a field
gets assigned to null.
This change aims to ensure that every stable method on Player,
ExoPlayer and ExoPlayer.Builder that takes a non-null type will fail
with an NPE before returning.

* Introduced `useHdr` for `GlEffect#toGlTextureProcessor`, so
`TextureProcessor` implementations can decide how to handle HDR.
* Creating FP16 color textures for HDR input.
Tested via manual testing, adding a no-op GlEffectWrapper to the transformation to
force use of intermediate textures, adding a linear ramp to the fragment shader,
and trying to ascertain that there's a real reduction in posterization when
switching from 4-bit to 8-bit unsigned bytes, and again from 8-bit unsigned bytes
to 16-bit floating point.
