To support multi-period content we need to store AdPlaybackStates and
SharedMediaPeriod by the periodUid as a key. While after this no-op CL,
we still only support single-period content, storing these resources by
periodUid is the ground work for multi-period support being added in an
follow-up CL.

We check the fraction of the available duration we have already
buffered for live streams to see if we can increase the quality.
This fraction compares against the overall available media duration
at the time of the track selection, which by definition can't include
one of the availabe chunks (as this is the one we want to load next).
That means, for example, that for a reasonable live offset of 3 segments
we can at most reach a fraction of 0.66, which is less than our default
threshold of 0.75, meaning we can never switch up.
By subtracting one chunk duration from the available duration, we make
this comparison fair again and allow all live streams (regardless of
live offset) to reach up to 100% buffered data (which is above our
default value of 75%), so that they can increase the quality.

Make audio track min buffer size configurable.
Move the code in its own class as DefaultAudioTrack
is getting very big. It also help for testability.
The new class is easily configurable and highly tested.
Manual test was used to catch any regression.

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.

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.

Currently, TrackSelectionOverrides are documented as being applied
per track type, meaning that one override for a type disables all
other selections for the same track type. However, the actual
implementation only applies it per track group, relying on the
track selector to never select another renderer of the same type.
This change fixes DefaultTrackSelector to fully adhere to the
TrackSelectionsOverride definition. This solves problems when
overriding tracks for extension renderers (see Issue: google/ExoPlayer#9675)
and also simplifies a workaround added to StyledPlayerView.

The asynchronous MediaCodec adapter queues input buffers in a
background thread. If a codec queueuing operation throws an exception,
the buffer enqueuer will store it as a pending exception and re-throw it
the next time the adapter will attempt to queue another input buffer.
The buffer enqueuer's flush() and shutdown() may throw an exception if
the pending error is set. This is subject to a race-condition in which
the pending error can be set while the adapter is flushing/shutting down
the enqueuer, e.g., if an input buffer is still being queued and the
codec throws an exception. As a result, the adapter cannot flush or
shutdown gracefully.
This change makes the buffer enqueuer to ignore any pending error
when flushing/shuttinf down so that the adapter can flush/release
gracefully even if a queueing error was detected.

When operating the MediaCodec in asynchronous mode, after a
MediaCodec.flush(), we start MediaCodec in the callback thread,
which might trigger errors in some platforms. This change adds an
experimental flag to move the call to MediaCodec.start() back to the
playback thread.

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.

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.

This helps to prevent issues where decoders can't handle negative
timestamps. In particular it avoids issues when the media accidentally
or intentionally starts with small negative timestamps. But it also
helps to prevent other renderer resets at a later point, for example
if a live stream with a large start offset is enqueued in the playlist.

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.

The current API exposes an `ImmutableMap` of
`TrackGroup` -> `TrackSelectionOverride`.
This has several disadvantages:
- A difficult to use API for mutation
(`ImmutableMap.Builder` doesn't support key removal).
- There is no track selection specific methods,
how the generic map API mapps to the selection override is not complex
but to obvious for a casual reader.
- The internal data type is exposed, making internal refactor difficult.
This was done to have the API ready as quick as possible.
When transitioning the clients to the map API in <unknown commit>,
it became clear that the map API was too verbose and not mapping
to the clients needs, so utility methods
were added to make operations clearer and more concise.
Nevertheless, having to use utility method to use easily and correctly
an API is not the sign of a good API.
This cl refactors the track selection API for several improvements:
- Add a type `TrackSelectionParameters` that encapsulate the internal
data structure (map currently).
- For iteration, expose as a list.
- Add a `Builder` for easy mutable operations.
- Add track selection specific methods to avoid having utilities functions.
- Those operations are the same as `DefaultTrackSelector.Parameters`
for easier migration. (`setOverride` was renamed to `addOverride`)
- Move `TrackSelection` classes outside of `TrackSelectionParameters`
as their own top level classes.
The migration of the client code is straightforward as most of it
were already using the previously mentioned utility functions
that are now native methods.
The full migration has not been done yet, and is pending on this cl approval.

Common houses DataSource as an interface for reading data,
but most of the concrete implementations are in ExoPlayer.
This means that in practice, if an app wants to use a module
that reads using DataSource (e.g. extractor), they may be
forced to depend on ExoPlayer as well to get a concrete
implementation (e.g. FileDataSource). This change moves the
DataSource implementations into common to resolve this.

TracksInfo is very similar to
`MappingTrackSelector.MappedTracksInfo` with some
fields removed to simplify the Player API,
notably it doesn't expose the renderer concept.
A significant difference is the addition of a `selected` boolean
field which avoids having a separate `getCurrentTrackSelection`
API.
This cl is a part of the bigger track selection change,
splitted for ease of review.
In particular, the MediaSession implementation and UI usage
have been slitted in child cls.

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.
