* OpenGL automatically clamps the output colors to the [0, 1] interval.

The encoder color info [defaults](https://cs.android.com/android/platform/superproject/+/master:frameworks/av/media/libstagefright/foundation/ColorUtils.cpp;l=377;drc=891c19ccfa4953b5e5f7b87118e007b994d8074c) to a value that depends on the input resolution, but when tone-mapping is enabled we should always get BT.709 color space. Hard-code this constant for now to avoid behavior depending on the resolution. A future change should use the decoder output media format to populate the color info.

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 will allow effects preview in ExoPlayer to use the
Effect and FrameProcessor interface (and the interfaces
they depend on) without depending on transformer or the
future effects module.

* Sets KEY_HDR_STATIC_INFO from MediaFormat in the DefaultCodec.
* Adds checks in mediaparser to ensure color space, range, and transfer are valid
  values.

Use a URL with a `.test` tld (RFC 2606) to make it clear
it's an testing URL.

Despite unregistering the callback and clearing pending Handler
messages, the callback may still receive pending calls if they
are already triggered by the AudioTrack. Instead of asserting
that the track is correct, we should gracefully ignore stale
events.

MediaCodecRenderer allows passing HDR10+ out-of-bound metadata
with ApplicationVersion = 1.

Once a controller bound to a MediaSessionService unbinds, this service
may be destroyed immediately if this was the last bound controller and
the service isn't started in the foreground.

At the time of releasing the controller, there may still be pending
commands that need to be handled by the session service. These commands
may cause the session service to post a foreground notification to
keep it alive. So to avoid the destruction of the service while these
commands are still handled, we need to keep the controller bound.

We also add a timeout in case the session tasks are never completed
by the session implementation. In case the controller is destroyed,
the unbinding happens automatically by the system.

TransformationException error codes were previously tied to OpenGL
but other FrameProcessor implementations are possible. So this CL
renames the error codes.
Also, remove GL_INIT_FAILED error code, as FrameProcessor
implemenations may initialize resources on a background thread
after the factory method returns, so it's not obvious how to
distinguish between initialization failures and processing failures.

This allows non-GL effects to be passed to custom FrameProcessor
implementations.

Both are used in the public FrameProcessor interface, so they
should be public too.

Downsampled from 3840x2160 resolution videos using ffmpeg:

This is possible because SSIM increases monotonically with bitrate.

Just a misc nit, since I found the name a bit confusing, and figured
findEncoderWithClosestSupportedFormat might be more descriptive.

and allow it to  be customized using a setter on Transformer.Builder.
