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.

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).

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.

MediaSource can be reused with other Player instances after they
have been released, so we need to set the PlayerId when preparing
the source. Access can mostly be handled by the implementation in
BaseMediaSource.

And in a couple of related places.
This is for consistency with the rest of the codebase where
we exclusively use indices.

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.
