Events on the wrapper should be propagated to TransformerInternal as
soon as they occur, switching round the process so TransformerInternal
does not have to query MuxerWrapper.

This CL is a prerequisite for the child CL, where MuxerWrapper can
simplify the internal state and logic.

We might as well keep this enabled by default, rather than having to
manually toggle it on to investigate RTL issues like Issue: androidx/media#227.

Before, it was possible for onDurationUs() and onAllTracksRegistered()
to be called before onTrackAdded() because they are called from
different threads. onDurationUs() and onAllTracksRegistered() are called
from the Transformer internal thread, and onTrackAdded() is called from
the playback thread.

This is useful if an app passes a custom AssetLoader that can only
output encoded or decoded samples.

Did not do this optimisation for `AdPlaybackState.AdGroup` as its length is zero for `AdPlaybackState` with no ads.

No need to pass default values while fetching keys, which we always set in `AdPlaybackState.AdGroup.toBundle()`.

Added another check in test to make sure we don't add keys to bundle for fields with `null` values.

AssetLoader declares the tracks with a setTrackCount() method. Setting
the track count on the MuxerWrapper is easier than calling
registerTrack() as many times as the number of tracks.

AssetLoader declares the tracks with a setTrackCount() method. Setting
the track count on the FallbackListener is easier than calling
registerTrack() as many times as the number of tracks.

The TransformationRequest passed to FallbackListener (and
createSupportedTransformationRequest) can have null for values that
are inferred from source. Within fallback, this can be height, width,
video mime type and audio mime type (HDR mode is not linked to source).
requestedFormat has these values populated from source, and
supportedFormat then finds the closest supported values to the
requested.

If any of the values in supportedFormat do not match the
requestedFormat, then this method would build upon the
TransformationRequest and update ALL possible fallback fields. This is
a problem because the fallback listener compares the original request
to the fallback one and notifies about all the fields that have
changed.

This CL changes this so that only the values that are not the same as
requested are changed in the supported request that is given to the
fallback listener.

When trying to run the test on Android Studio, error "incompatible
types: Buffer cannot be converted to ByteBuffer" is logged. This is
because ByteBuffer.flip() returns a Buffer (and not a ByteBuffer).
Annotation @CovariantReturnType on ByteBuffer.flip() should resolve this
automatically but it doesn't seem supported at the moment.

There are two overloads of this method due to a type 'rename' from
`PlayerControlView.VisibilityListener` to
`PlayerView.ControllerVisibilityListener`. Currently when you call one
overload it passes `null` to the other one (to clear the other listener).
Unfortunately this results in it clearing itself, because it receives
a null call back!

This change tweaks the documentation to clarify that the 'other'
listener is only cleared if you pass a non-null listener in. This solves
the recursive problem, and allows the 'legacy' visibility listener to be
successfully registered.

Users of this class may run into these assertions when creating the
State and they need to check the source code to understand why
the State is invalid. Adding error messages to all our correctness
assertions helps to understand the root cause more easily.

This CL replaces concurrent collections and atomic primitives with a single
lock, this way the code is easier to reason about.

Note that we simply use GlEffectsFrameProcessor in-app / GL tone-mapping, so PQ->SDR tone-mapping isn't yet implemented.

Tested manually using the demo on Pixel 7, to confirm that device and in-app tone
mapping behave similarly.

Adds the AudioMixerAlgorithm interface which allows for specialized
implementations of audio mixing that also efficiently convert between
source and mixing formats.

Initial implementation has two algorithms:
1. Float -> float (with channel mixing)
2. S16 -> float (with channel mixing)

To do that, rename PROGRESS_STATE_NO_TRANSFORMATION to
PROGRESS_STATE_NOT_STARTED and update Javadoc of ProgressState to not be
Transformer specific.

This should allow us to focus on HDR failures instead of network buffering
failures when debugging HDR issues.

These files are each used on several files, so it should be more worth the
test binary impact to move these files to local first.

Locally, tests did take less time after this diff

The MediaSourceFactory won't be used by the other AssetLoaders

In order to do that, ExoPlayerAssetLoader has been made public, and the
DefaultAssetLoaderFactory has become a wrapper around
ExoPlayerAssetLoader.

These are the remaining setter operations. They all share the same
logic that handles playlist and/or position changes. The logic to
create the placeholder state is mostly copied from ExoPlayerImpl's
maskTimelineAndPosition and getPeriodPositonUsAfterTimelineChanged.
