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.

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.

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.

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

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

Size requires API 21. Using Pair instead will allow effects to be
used from API 18 during previewing once they are moved out of
transformer.

This is needed for applying effects to a playlist.

The effects are applied based on the presentation time of the
frame in its corresponding media item and the offset is added
back before encoding.

Each time the offset changes, end of input stream is signalled
to the texture processors. This is needed because the texture
processors can expect monotonically increasing timestamp within
the same input stream but when the offset changes, the timstamps
jump back to 0.

It's always safe to ignore the result of these methods, because the
caller already has a reference to the returned value.

This allows us to use BT.2020 RGB linear for intermediate shaders, which also
allows us to re-enable PeriodicVignetteProcessor, which should work properly in
linear color-spaces.

Manually tested by adding a GlEffectsWrapper, and confirming that HLG HDR editing still looks correct.

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.
