Improves the time taken to construct `playerInfo` from its bundle from ~450 ms to ~400 ms. Each `MediaItem` inside `Timeline.Window` contains `MediaMetadata` and hence is a good candidate for bundling optimisations. There already exists a test to check all parameters for null values when unset.

The TransformationResult has some useful values that are set in error
cases, such as the codecs used.

It covers the following cases:

| From/To     | `null` | `surface 0` | `surface 1` |
|-------------|--------|-------------|-------------|
| `null`      | 🆖      | 📺           | 📺           |
| `surface 0` | ❌      | 🔁           | 📺           |
| `surface 1` | ❌      | 📺           | 🔁           |

Where
- 🆖 means NOP
- ❌ means
  - Set `null` on FrameProcessor, effectively dropping all frames
- 📺 means
  - Notify the listener of video size
  - Set FrameProcessor output surface and size when MSG_SET_VIDEO_OUTPUT_SIZE is received
- 🔁 means
  - Notify the listener of video size

Adds COLOR_TRANSFER_GAMMA_2_2, to match behavior in other HDR to SDR tone mapping
implementations.

This simplifies some position tracking needs for an app implementing
SimpleBasePlayer.
 - The period index can always be derived from the media item index
   and the position. So there is no need to set it separately.
 - The media item index can be left unset in the State in case the app
   doesn't care about the value or wants to set it the default start
   index (e.g. while the playlist is still empty where UNSET is
   different from zero).
 - Similarly, we should allow to set the content position (and buffered
   position) to C.TIME_UNSET to let the app ignore it or indicate the
   default position explictly.

This ensures they are not accidentally triggered again when
the state is rebuilt with a buildUpon method.

Otherwise, the decoders are not captured. It works at the moment for the
video decoder because decoding is still done on the sample pipeline but
it will moved to the AssetLoader soon.

`AudioProcessor`s expect direct buffers. This shouldn't make any functional difference in our code, but a custom audio processor might try to access the buffer from JNI in which case a direct byte buffer is more efficient.

This simplifies the caller slightly.

This is so that apps can customise AssetLoader

`SilentAudioGenerator` could output a fractional audio frame, and this could cause downstream components to throw because of trying to read a complete audio frame but only seeing a partial one.

Calculate the output buffer size based on the frame size (which is a no-op for stereo 16-bit audio) and calculate a total number of frames to output then multiple by the frame size.

isLoading is not allowed to be true when IDLE, so we have to set to
false when stopping in case it was set to true before.

BasePlayer simplifies implementations by handling all the various
seek methods and forwarding to a single method that can then be
implemented by subclasses. However, this loses the information about
the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.

This is a step towards allowing apps to inject a custom AssetLoader

- Use a single `VideoSize` instance instead of four primitive fields.
- Clarify that the reported size is the decoded size, that is the encoded video
  size.

calls setbounds() on the drawable as the bounds of a drawable must be set for the .draw() method to work as noted in the [Drawable Documentation](https://developer.android.com/reference/android/graphics/drawable/Drawable#draw(android.graphics.Canvas)).

Also fixes createStaticDrawableOverlay() not taking specified overlay settings into account.

The duration in TransformerInternal.ComponentListener is set on the
Transformer internal thread, and is read on the playback thread. Making
this field volatile ensures that the playback thread reads the updated
value.

Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.

Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.

Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

It looks like this was added accidentally in <unknown commit>.

An AndroidTest is needed to test the message sending from ExoPlayerImpl to
a video renderer (MCVR in this case). The test will be added later.

The folder type has a mix of information about the item. It shows
whether the item is browsable (type != FOLDER_TYPE_NONE) and
which Bluetooth folder type to set for legacy session information.

It's a lot clearer to split this into a boolean isBrowsable and
use the existing mediaType to map back to the bluetooth folder type
where required.

folderType is not marked as deprecated yet as this would be an API
change, which will be done later.

This adds support for the release handling. To align with the
established behavior in ExoPlayer, the player can only call
listeners from within the release methods (and not afterwards)
and automatically enforces an IDLE state (without listener call)
in case getters of the player are used after release.
