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.

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.

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.

The DefaultMediaNotificationProvider caches the last loaded artwork
bitmap so that the bitmap isn't loaded again when the notification is
updated, e.g., the player is transiting from playing to paused. However,
loading bitmap requests for bitmaps that are already being loaded are
not suppressed. For example, if the notification is updated while the
artwork is still downloading, the same artwork might be downloaded
multiple times.

This change suppresses a bitmap load request if the same artwork is
still being loaded, to avoid additional artwork downloads.
