This is required before we can move CEA-6/708 parsing from the rendering
side of the sample queue to the extraction side.
This re-ordering is needed for video encodings with different decoder
and presentation orders, because the CEA-6/708 data is attached to each
frame and needs to be processed in presentation order instead of decode
order. This change re-orders frames within a group-of-pictures, but also
takes advantage of `maxNumReorderFrames/Pics` values to cap the size of
the re-ordering queue, allowing caption data to be released 'earlier'
than the end of a GoP.
Annex D of the CEA-708 spec (which also applies for CEA-608 embedded in
SEI messages), makes the need to re-order from decode to presentation
order clear.

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.

Add the following NAL unit parsing utility functions that will be needed for the MV-HEVC support as proposed in Apple's HEVC stereo video interoperability profile:
- NAL unit header parsing to get the layer information needed for MV-HEVC support.
- VPS parsing, including vps_extension() needed for MV-HEVC support.
- SPS parsing modifications to support MV-HEVC.

Upon track transition of offloaded playback of gapless tracks, the framework will reset the audiotrack frame position. The `AudioTrackPositionTracker`'s `AudioTimestampPoller` must be made to expect the reset and cache accumulated sum of `AudioTimestamp.framePosition`.

The user might expect this button to back out to the configuration activity,
but actually it toggles pause/resume (though `cancel` is the method called).

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.

Setting a `null` value doesn't remove the key as expected per the `MediaFormat` API documentation, using the `removeKey` method instead which is only available starting API level 29.

ExoPlayer used to call `stop()` before `release()`. This was removed in
<unknown commit>.
A framework bug introduced in Android 11 (API 30) resulted in some
DRM -> clear transitions failing during `MediaCodec.configure()`. An
investigation in Issue: google/ExoPlayer#8696 and b/191966399 identified that this was
due to `release()` returning 'too early' and the subsequent
`configure()` call was then trying to re-use a `Surface` that hadn't
been fully detached from the previous codec. This was fixed in
Android 13 (API 33) with http://r.android.com/2094347.
ExoPlayer worked around the framework bug by adding an arbitrary 50ms
sleep after a failed codec initialization, followed by retrying. This
was enough to resolve the problem in the test scenario on a OnePlus
AC2003.
Issue: androidx/media#1497 points out that 50ms might not be the appropriate delay
for all devices, so it's an incomplete fix. They suggested re-adding the
`MediaCodec.stop()` call instead. This also reliably resolves the issue
on the OnePlus AC2003 (with neither workaround in place, the problem
repros almost immediately).

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.

The two arrays need to have the same length and the selection
must match in their nullness (unless for TYPE_NONE
renderers). Clarify this more clearly in the docs and add
new asssertions for it. This avoids that the player is failing
in obscure ways much later.

The test is flaky because the decoding process in the renderer
depends on some timing from MediaCodec beyond our control and
the new keyframe added in the test is sometimes 'dropped' when
it arrives too late.
We can fix this by controlling the test progress a bit more
tightly: first rendering with the same current time until the
key frame is processed and then start increasing the time
until we've reached the end.

Summary:
This change aims to add a generic `CustomData` field to the `Format` class.
The intent is to allow ExoPlayer customers to add extra data to the Format class without forcing
specific data to be included, impacting customers that do not need it and would allow for the data
to be changed without requiring changes to the `Media3` codebase.
