Using chunkless preparation greatly improves start up time if the master
playlist declares CODECS for the renditions. Hence, we turn this on
by default as it benefits most well-defined HLS master playlists.
The only known reason why developers may want to turn this feature off is
when the renditions contain muxed closed-caption tracks that are not
declared in the master playlist. So this change also updates the documentation
and RELEASENOTES to point out this caveat.

Allowing duplicate groups caused some other code working with the
array to use reference equality comparison. This is error-prone,
easily forgotten (e.g. when using the TrackGroups in a map) and
causes bugs when TrackGroups are serialized to disk or to another
process.
All TrackGroups created by ExoPlayer are already unique and custom
code creating TrackGroupArrays with identical groups can easily
distringuish them by adding an id to each group.

This will remove the need to implement compat code handling very old API
versions where some symbols are not available, and it reduces the burden of
dealing with media framework issues around concurrent codec usage that are
worse on older API versions. Top apps that we've surveyed as potential users
for transformer library features are using API 21 or later.

Currently we prefer technical preferences set in the Parameters over
content preferences implied by the media. It proably makes more
sense in the opposite order to avoid the situation where a
non-default track (e.g. commentary) is selected just because it
better matches some technical criteria.
Also add comments explaining the track selection logic stages.

And also tweak existing role flag logic to strictly prefer perfect
matches over partial matches.
Caveat: Video role flags only supported for fixed track selections
(same issue as Issue: google/ExoPlayer#9519).

After removing the deprecated call to player.stop(/* reset= */ true) and instead using two calls to the player, overridding stop in a ForwardingPlayer does not help to avoid clearing the player. To remove the deprecation we need an option so that users who want not to clear the player have a way to do so.

The player will not play ads in final states (played, skipped, error)
again. To allow ads loader customizations to play ads again, we can
add a method that resets the state back to available or unavailable
(depending on whether we have the URI for the ad).

Currently, DrmSessionManager takes player specific values (= the
playback looper) through (pre)acquireSession calls and requires
the caller to pass in the same values every time.
Instead, we can configure the DrmSessionManager for playback with
a player once before it's being used. We can't simply extend the
prepare() method as prepare may be called before the player is
created to prewarm the DrmSessionManager.
The new method also takes a PlayerId which is bound to the lifetime
of the player similar to the playback looper.
To avoid breakage of custom MediaSources with DRM, we can keep the
old the SampleQueue.createWithDrm method as deprecated.

Populate ICY headers into MediaMetadata so that they can
propagate to the app via AnalyticsListener#onMediaMetadataChanged().
This change copies IcyHeaders.name into MediaMetadata.description
and IcyHeaders.genre into MediaMetadata.genre.
Note: MediaItem.metadata maintain their precedence and overwrite any
ICY headers parsed.

When we have multiple overrides for TrackGroups associated with
one renderer, we need to look at all of them to find the non-empty
one. Empty ones should only be used to remove previously selected
tracks for this group and otherwise be ignored.
Currently this is broken because the first override (no matter if
it's empty or not) is used as the final selection for this renderer.

Add protected method DefaultRenderersFactory.getCodecAdapter(), so that
subclasses of DefaultRenderersFactory that override
buildVideoRenderers() or buildAudioRenderers() can access the
DefaultRenderersFactory codec adapter factory and pass it to
MediaCodecRenderer instances they may create.

Where this introduced an inconsistency (e.g. assigning to something
called `windowIndex`), I generally renamed the transitive closure of
identifiers to maintain consistency (meaning this change is quite
large). The exception is code that interacts with Timeline and Window
directly, where sometimes I kept the 'window' nomenclature.

Test file produced with:
$ MP4Box -add "sample.mp4#video:colr=nclc,1,1,1" -new sample_18byte_nclx_colr.mp4
And then manually changing the `nclc` bytes to `nclx`.
This produces an 18-byte `colr` box with type `nclx`. The bitstream of
this file does not contain HDR content, so the file itself is invalid
for playback with a real decoder, but adding the box is enough to test
the extractor change in this commit.
(aside: MP4Box will let you pass `nclx`, but it requires 4 parameters, i.e. it
requires the full_range_flag to be set, resulting in a valid 19-byte colr box)

The static and dynamic metadata now build up in a list, such that when
the MediaMetadata is built, they are applied in an event order. This
means that newer/fresher values will overwrite older ones. The MediaItem
values are then applied at the end, as they take priority over any other.

Issue: #9392 reports occasional IllegalStateExceptions from release()
in crashlytics,`with no way to reproduce locally. It seems likely there
is a bug somewhere in DRM handling, and ideally we would find that and
fix it.
However we haven't been able to find the problem, and in the meantime
these exceptions cause the entire app to crash. Although this is
arguably useful from a debugging perspective, it's obviously a poor
experience for developers and users, since all we're actually trying to
do is release the session, so maybe we shouldn't strictly care that it's
already released?
This change replaces the exception with an error log, which might be a
useful debugging hint if we see other DRM unexpected behaviour due to
references to released sessions being held for too long.

This change makes asynchronous queueing non-experimental, it enables the
feature by default on devices with API level >= 31 (Android 12+) and
exposes APIs for apps to either fully opt-in or opt-out from the
feature.
The choice to use or not asynchronous queueing is moved out of
MediaCodecRenderer to a new MediaCodecAdapter factory, the
DefaultMediaCodecAdapterFactory. This is because, at the moment,
if an app passes a custom adapter factory to a MediaCodecRenderer and
then enables asynchronous queueing on it, the custom
adapter factory is not used but this is not visible to the user.
The default behavior of DefaultMediaCodecAdapterFactory is to create
asynchronous MediaCodec adapters for devices with API level >= 31
(Android 12+), and synchronous MediaCodec adapters on devices with older
API versions.
DefaultMediaCodecAdapterFactory exposes methods to force enable or force
disable the use of asynchronous adapters so that applications can enable
asynchronous queueing on devices with API versions before 31 (but not
before 23), or fully disable the feature. For applications that build
MediaCodecRenderers directly, they will need to create a
DefaultMediaCodecAdapterFactory and pass it to the renderer constructor.
For applications that rely on the DefaultRenderersFactory, additional
methods have been added on the DefaultRenderersFactory to control
enabling/disabling asynchronous queueing.
