Renderers may be enabled for subsequent media items as soon as the current media item's renderer's isEnded() returns true. When a renderer is being enabled and the player is 'playing', that renderer is also started. When playing a mixed playlist of images and content with audio & video, the player may skip some image items because the early-starting of the audio renderer causes a clock update.
A solution is to only start the "early-enabled" renderers at the point of media transition and add a condition on DefaultMediaClock to use the standalone clock when reading-ahead and the renderer clock source is not in a started state.

When the controller replaces the current item, the masking position will be changed to the default position of the new item for a short while, before the correct position comes from the session. This will interrupt the current position fetched from the controller when the playback doesn't interrupted by the item replacing.

(cherry picked from commit 1bdc58de0b)
This change aims to prioritise tracks that have a 'smooth enough for
video' frame rate, without always selecting the track with the highest
frame rate.
In particular MP4 files extracted from motion photos sometimes have two
HEVC tracks, with the higher-res one having a very low frame rate (not
intended for use in video playback). Before this change
`DefaultTrackSelector` would pick the low-fps, high-res track.
This change adds a somewhat arbitrary 10fps threshold for "smooth video
playback", meaning any tracks above this threshold are selected in
preference to tracks below it. Within the tracks above the threshold
other attributes are used to select the preferred track. We deliberately
don't pick the highest-fps track (over pixel count and bitrate), because
most users would prefer to see a 30fps 4k track over a 60fps 720p track.
This change also includes a test MP4 file, extracted from the existing
`jpeg/pixel-motion-photo-2-hevc-tracks.jpg` file by logging
`mp4StartPosition` in
[`MotionPhotoDescription.getMotionPhotoMetadata`](b930b40a16/libraries/extractor/src/main/java/androidx/media3/extractor/jpeg/MotionPhotoDescription.java (L123))
and then using `dd`:
```
mp4StartPosition=2603594
$ dd if=jpeg/pixel-motion-photo-2-hevc-tracks.jpg \
of=mp4/pixel-motion-photo-2-hevc-tracks.mp4 \
bs=1 \
skip=2603594
```
----
This solution is in addition to the `JpegMotionPhotoExtractor` change
made specifically for these two-track motion photos in
5266c71b3a.
We will keep both changes, even though that change is not strictly
needed after this one, because adding the role flags helps to
communicate more clearly the intended usage of these tracks. This
change to consider FPS seems like a generally useful improvement to
`DefaultTrackSelector`, since it seems unlikely we would prefer a 5fps
video track over a 30fps one.

Some devices supporting Performance Points for decoder coverage are missing coverage over the CDD requirements for H264. For these cases ExoPlayer should fall back to legacy resolution and frame rate support checks. If there is a stream evaluated as a PerformancePointCoverageResult of COVERAGE_RESULT_NO, then ExoPlayer checks for coverage of the 720p H264 CDD requirement.

If the reading period has already advanced and a track reselection procs that only affects the reading period media, then ExoPlayer may try and apply the reading period's track selection incorrectly unto the playing period. ExoPlayer should apply the playing period's track selection to the playing period instead.

The `PreloadMediaPeriod.selectTracksForPreloading` can be called for multiple times at the preloading stage (before the period is being played). For example, when the period resumes preloading. This change fix the assertion failure in `ProgressiveMediaPeriod.selectTracks` caused by the wrong implementation of `PreloadMediaPeriod.selectTracksForPreloading` when it is trying to retain the previously preloaded streams.
Also the `TrackSelectorResult` parameter is changed to a list of `ExoTrackSelection`. We should compare the selections only rather than considering the `RendererConfiguration` in the `TrackSelectorResult` to decide whether to retain the streams, as for preloading case the renderers haven't consumed the samples yet.

The updated algorithm has two main improvements:
- The silence padding is not constant but a ratio of the original
silence (up to a defined max) to more naturally represent the
original gaps.
- The silence is not instantly going to zero, but uses a ramp down
and up for a smooth volume transition and also retains a small
percentage of the original noise for more natural "silences" that
still contain some background noise.

Subclasses of this component can customize it by wrapping with the
decorator pattern, and a custom `CompositeSequencableLoaderFactory`
allows access to the list of delegate `SequenceableLoader` instances.
The `final` keyword was removed as part of <unknown commit> but this
component never ended up being subclassed within the library.
Making this class `final` makes upcoming changes easier to reason
about.

The seek table in a Xing/Info header is very imprecise (max resolution
of 255 to describe each of 100 byte positions in the file). Seeking
using a constant bitrate assumption is more accurate, especially for
longer files (which exacerbates the imprecision of the Info header).
VBR files should contain an Xing header, while an Info header is
identical but indicates the file is CBR.

This behavior was previously available as opt-in via
`MediaItem.DrmConfiguration.Builder.setPlayClearContentWithoutKey` and
`DefaultDrmSessionManager.Builder.setPlayClearSamplesWithoutKeys`. This
change flips the default of both these properties to true.
This should speed up the time for playback to start when playing DRM
content with a 'clear lead' of unencrypted samples at the start.
Previously playback would wait until the keys for the later encrypted
samples were ready. The new behaviour could result in mid-playback
stalls/rebuffers if the keys are not ready yet by the transition from
clear to encrypted samples, but this is not really a regression since
previously playback wouldn't have started at all at this point.

When the media notification controller is requested for a session
with `getConnectedControllerForSession` and the `Future` is not null
but not yet completed, the `Future` was returned either way. This was
reported as creating a race condition between the notification
being requested for update the very first time, and the media
notification controller having completed connecting to the session.
Returning null from `getConnectedControllerForSession` when the
`Future` is available but not yet done fixes the problem. This is
safe because for the case when a notification update is dropped,
the media notification controller will trigger the update as soon
as the connection completes.
