* 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.

This may happen when a containers' color transfer incorrectly does not match
the video's color transfer.

An example of a file with such a mismatch is the current Transformer demo HDR10
sample file.

Manually tested by confirming that no errors are emitted for SDR and HLG sample
files, and that errors are emitted for our incorrect HDR10 sample file.

- Update profile selection logic to pick an HDR-compatible profile when doing HDR editing on H.264/AVC videos.
- Handle doing the capabilities check for all MIME types that support HDR (not just H.265/HEVC).
- Fix a bug where we would pass an HDR input color format to the encoder when using tone-mapping.
- Tweak how `EncoderWrapper` works so decisions at made at construction time.

Manually tested cases:
- Transformation of an SDR video.
- Transformation of an HDR video to AVC (which triggers fallback/tone-mapping on a device that doesn't support HDR editing for AVC).
- Transformation of an HDR video with HDR editing.

The old URL doesn't correctly signal the HDR10 color info in the container.

The new URL signals ST2084 (PQ) transfer function and BT.2020 color space as expected.

Also remove VideoEncoderSettings.colorProfile as there are no
concrete use cases for customizing this and it clashes with picking
the color format automatically based on SDR vs. HDR.

The call doesn't currently reset the already loaded suppliers and
factories. Also fix the supplier loading code to use a local copy
of the current dataSourceFactory to avoid leaking an updated
instance to a later invocation.

We currently start a simple Thread to release AudioTracks
asynchronously. If many AudioTracks are released at the same
time, this may lead to OOM situations because we attempt to
create multiple new threads.

This can be improved by using a shared SingleThreadExecutor.
In the simple case of one simmultaneous release, it's exactly
the same behavior as before: create a thread and release it
as soon as it's done. For multiple simultanous releases we
get the advantage of sharing a single thread to avoid creating
more than one at the same time.

Leaving the media item that has been passed in unchanged, ensures that the
media item in the timeline is equal to the media item that the user has
passed into the player. The value of the tag is the uid of the window,
meaning this is redundant information.

`HevcConfig.parse` misreads reserved bit to determine NAL unit type. This is currently meant to be always set to 0, but could be given some kind of meaning in a future revision.

Some calls to handleBuffer return false while a previous
flush is still handled in the background.

Fix this by either asserting the method returns true if
we don't expect any delay, or calling it repeatedly until
it returns true (within a timeout).

I don't think it's useful to keep these in numerical order, it makes
more sense to keep them grouped into a 'logical' ordering.

This extension is needed for editing HDR input with OpenGL, as the
ExternalTextureProcessor samples raw YUV values from the
external texture for HDR and converts them to RGB itself rather than
relying on the OpenGL driver to do this automatically as for SDR.

The media item needs to be assigned to `Window.mediaItem` in `CastTimeline.setWindow`. For this the `MediaItem` needs to be available in the timeline.

When a `MediaItem` is passed to the `set/addMediaItems` method, we can't yet know the Cast `MediaQueueItem.itemId` that is generated on the device and arrives with an async update of the `RemoteMediaClient` state. Hence in the `CastTimelineTracker`, we need to store the `MediaItem` by Casts's `MediaItem.contentId`. When we then receive the updated queue, we look the media item up by the content ID to augment the `ItemData` that is available in the `CastTimeline`.

We wait until a previous AudioTrack has been released before
creating a new one. This is currently done with a thread
block operation, which may cause ANRs in the extreme case
when someone attempts to release the player while this is
still blocked.

The problem can be avoided by just returning false from
DefaultAudioSink.handleBuffer to try again until the previous
AudioTrack is released.

Reproduction steps to force the issue:
1. Add Thread.sleep(10000); to the AudioTrack release thread.
2. Add this to the demo app:
    private int positionMs = 0;

    Handler handler = new Handler();
    handler.post(new Runnable() {
      @Override
      public void run() {
        player.seekTo(positionMs++);
        if (positionMs == 10) {
          player.release();
        } else {
          handler.postDelayed(this, 1000);
        }
      }
3. Observe Player release timeout exception.

These steps can't be easily captured in a unit test as we can't
artifically delay the AudioTrack release from the test.

The SDR constant also specified a color space and range, in addition to
C.COLOR_TRANSFER_SDR. However, it turns out that SDR videos may use different color
space and range values, so following prior ExoPlayer conventions to have `null`
mean "generic SDR" is preferable here.
