During a seek, or when playing a media with clipped start,
MCVR encounters preroll decode-only buffers that are not rendered.
Use C.BUFFER_FLAG_NO_OTHER_SAMPLE_DEPENDS_ON_THIS to determine
whether a decode-only buffer is unused as reference.
These buffers can be dropped before the decoder.
When this optimization is triggered, increment
decoderCounters.skippedInputBufferCount.
Tested in ExoPlayer demo app on "One hour frame counter (MP4)"
after enabling extractorsFactory.setMp4ExtractorFlags(
FLAG_READ_WITHIN_GOP_SAMPLE_DEPENDENCIES);
Observe: "sib" increases on each seek.

Once a service is started as a foreground service, it must
be started into the foreground. This means an app can not
suppress a play command arriving from the `MediaButtonReceiver`
once the receiver has started the service.
This change adds a method to the `MediaButtonReceiver` that
allows app to suppress starting the service to not get into
this situation of wanting to suppress the play command after
the service is already started.

Upon the call of `PreloadMediaSource.preload`, the source will periodically check the source refresh or period loading error, and trigger `PreloadMediaSource.PreloadControl.onPreloadError`. For now, the `DefaultPreloadManager` will skip the problematic source and continue to preload the next source. The checking of the error will be terminated when the source stops preloading or releases.

This utility helps apps to forward to another Player while overriding
selected behavior or state values. The advantage to a ForwardingPlayer
is that the SimpleBasePlayer base class keeps ensuring correctness,
listener handling etc.
The default forwarding logic tries to stay as close as possible to the
original method calls, even if not strictly required by the Player
interface (e.g. calling single item addMediaItem instead of
addMediaItems if only one item is added).

The Timeline, Tracks and MediaMetadata are currently provided
with a list of MediaItemData objects, that are a declarative
version of these classes. This works well for cases where
SimpleBasePlayer is used for external systems or custom players
that don't have a Timeline object available already. However,
this makes it really hard to provide the data if the app already
has a Timeline, currently requiring to convert it back and forth
to a list of MediaItemData.
This change adds an override for `State.Builder.setPlaylist`
that allows to set these 3 objects directly without going
through MediaItemData. The conversion only happens when needed
(e.g. when modifying the playlist).

The value is basically a duplicate of the information stored
in the timeline field. Reducing the source of truth to the
single Timeline also allows acceptance of other Timelines in the
future that don't necessarily have the helper structure of
the playlist.
To allow apps to retrieve the current playlist as it is, we
add a getter instead.

The percentage should be interpreted as relative to the size of a parent
node.
This change makes this inheritance work correctly for percentages in
both the parent and child. It does not fix the case of a non-percentage
parent size with a percentage child size.

This is a new `DataSource` that can be used to read from a `FileDescriptor`.
Limitations:
- The provided file descriptor must be seekable via lseek.
- There's no way to duplicate a file descriptor with an independent position (it
would be necessary instead for the app to provide a new FD). Therefore this
implementation will only work if there's one open data source for a given file
descriptor at a time.

Deprecate `setInputDefaultBufferSize` and `setRequireRegisteringAllInputFrames`
as the new input stream type replaces these (as far as we know they are always
used together).
This is in preparation for supporting asset loaders signaling that they require
these features, specifically for recording from a surface.

This change extends the error replication to a given set of
error codes (not only authentication error), but only
replicates an error if the caller of the service `Callback`
is a legacy controller. It also makes error replication
configurable so that apps can opt-out and report errors
manually instead, or define the error codes for which
replication is enabled.
The change also removes the restriction of `sendError` only
being available for Media3 controllers. Instead, sending an
error to a legacy controller updates the platform playback
state in the same way as sending the error to the media
notification controller.

When handling a playback error that originates from a future item in
the playlist, we added support for jumping to that item first,
ensuring the errors 'happen' for the right 'current item'.
See 79b688ef30.
However, when we add this new position discontinuity to the
playback state, there may already be other position discontinuities
pending from other parts of the code that executed before the
error. As we can't control that in this case (because it's part
of a generic try/catch block), we need to send any pending
updates first before handling the new change.

Extractors should not report additional tracks once they called
ExtractorOutput.endTracks. This causes thread safety issues in
ProgressiveMediaPeriod where the array of sample queues is
extended while the playback thread accesses the arrays.
Detecting this problem early is beneficial to avoid unexplained
exceptions later one. In most cases where this may happen (namely
TS extractors finding new tracks), it's better to ignore the new
tracks instead of failing completely. So this change adds a
warning log message and assigns a placeholder output.
Note: The same workaround already exists in HlsSampleStreamWrapper
and MediaExtractorCompat.

Images are rendered into an ImageView (on top of the video shutter).
The image view is set to the images emitted by ExoPlayer's ImageOutput
and cleared when there is no longer a selected image track.
In order to keep the existing behavior of video tracks to only clear
the old output once the new first frame is rendered (avoiding short
periods of black between playlist items), we have to reorder this code
slightly to make it work for video and images. Both are treated in the
same way. If both are enabled, video takes precedence.
As the UI module only depends on the common module, we can't direcly
add the ImageOutput to ExoPlayer. This is done via reflection if
the provided Player is an ExoPlayer.

A fatal `PlaybackException` is mapped to a legacy playback state
in state `STATE_ERROR` with error code, message and extras. A
non-fatal error sent to controllers with `MediaSession.sendError`
is synced to the legacy session by setting error code and message
and merging the extras while preserving the rest of the state in
sync with the session player.
Vice versa, a `MediaController` connected to a legacy session receives
fatal errors through `Player.onPlayerErrorChanged()` and non-fatal errors
through `MediaController.Listener.onError()`.
Error codes are mapped in `LegacyConversions`. Values of error codes
in `@SessionError.ErrorCode` come from `@PlaybackExceptino.ErrorCode`
with the exception of `@SessionError.ERROR_IO` and
`@SessionError.ERROR_UNKNOWN`. These already exist in
`@PlaybackException.ErrorCode` and are mapped accordingly to avoid
semantic duplicates.

It's currently not possible to remove a previously set image output
on ExoPlayer, although the underlying renderer already supports
receiving null to clear the output. Marking the parameter as
nullable allows apps to clear it as well.

Rational for keeping field package private:
Since the overall export already very complex, by looking at the output file
its hard to know if the desired processing happened or not. Since we now
support sequences with "n" media items, its even more important to know if all
the media items were processed or not.
Although the field exposes implementation details, it seems ok as we get benefit of detailed testing.

This change adds `SessionError` and uses it in `SessionResult`
and `LibraryResult` to report errors to callers.
Constructors and factory method that used a simple `errorCode` to
construct error variants of `SessionResult` and `LibraryResult`
have been overloaded with a variant that uses a `SessionError`
instead. While these methods and constructors are supposed to be
deprecated, they aren't yet deprecated until the newly added
alternative is stabilized.
