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.

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.

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.

caller already has a reference to the returned value.

We currently clear all pending messages, including the one that flushes
pending commands to the MediaSession. To ensure all commands that have
been called before controller.release() are still sent, we can manually
trigger the flush message from the release call.

Related to handling the final flush because disconnecting the controller,
MediaSessionStub didn't post the removal of the controller to the
session thread, creating a race condition between removing the controller
and actually handling the flush.

These constructors are currently very intertwined, passing `this`
references from the constructor of one to the constructor of another
before the first constructor is complete (and so the `this` reference
isn't really valid yet).

This change uses checker framework `@UnderInitialization` and
`@NotOnlyInitialized` annotations to make it more clear that the
references are not available yet. For the one 'direct' access needed
in the second constructor (calling `getApplicationLooper()`) we now
pass the `applicationLooper` directly alongside (to avoid needing to
dereference the reference 'too early').

This change also ensures that where a class hierarchy has a
'dependent' class hierarchy, the 'subclass' instance is always used
(by both subclass and superclass) without casting or manually hiding
the superclass field, by defining an overridable `getFoo()` method
instead and always using it.

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.
