Float values are allowed to be > 0dbfs,
it is just not nominal as it will might
distort the signal when played without
attenuation.
This is also consistent with
[AudioTrack.write(FloatBuffer)](https://developer.android.com/reference/android/media/AudioTrack#write(float[],%20int,%20int,%20int)) that explicitly
allows it up to 3dbfs.

The method has been called from two call sites in EPII triggered by EPII.updatePeriods(). The first call site was calling it when the MediaSourceList is empty or not yet prepared. This can be removed because if empty or not prepared no source ever could have thrown yet.
The second call site was checking for potential source refresh exceptions when queue.getNextMediaPeriodInfo() returns null when trying to getting the next loading period. Looking into all reasons for why the method returns null, none of them is caused by an exception of a media source. The reasons are:
- if we are at the last period of the timeline
- if the defaultPosition of the next period in the timeline is null (if the window.durationUs == C.TIME_UNSET or defaultPositionProjectionUs is projected beyond the duration of the window)
- if we are waiting for an ad uri to arrive (period.isAdAvailable(...) == false)
- if we are waiting for the ad group count to be updated (adCountInCurrentAdGroup == C.LENGTH_UNSET)
The above reasons are not caused by a source error and may be resolved when doSomeWork is called the next time. Hence it is save to remove the calls to maybeThrowSourceInfoRefreshError().
Beside this, an actual sourceInfoRefreshError will be reported by maskingMediaSource.maybeThrowPrepareError(), which is called each time doSomeWork() is called and the playing period is not yet prepared (EPII:L836). So the player is notified by source errors that way, which confirms removing the above calls is fine.

Plumb this down into BaseRenderer.onStreamChanged and use it when
deciding whether to render the first frame of a new period.

This doesn't affect the nullness checker or Kotlin, but it does make
weird warnings appear in Android Studio. It seems mildly preferable to
have the same spurious warnings in these files that we have in other
tests, rather than different spurious warnings.

This change masks playbackInfo.periodId and playbackInfo.loadingPeriodId for operations which change these periods (set/add/remove sources and seeks).
Because this masking is reflected in the playbackInfo object, player attributes can be retrieved without the maskingXyz variables in EPI. This has the advantage that the playbackInfo object always reflects the public state of the player even when operations are still pending. The maskingXyz variables in EPI are only required for the deprecated use case of an initial seek in an empty timeline.

In order to use DeviceInfo class in media2, this CL moves the class to
common module. It didn't move the other file in the same package,
DeviceListener, as it's for DeviceComponent but media2 SessionPlayer
doesn't have components as it is already flattened. PlayerCallback will
have equivalent methods of DeviceListener.

The method currently advances the read position and returns the number
of skipped samples. This prevents checking how many samples are skipped
before the operation is executed.
Instead, we have a new method that returns the number of to be skipped
samples and a skip method that executes the skipping.

- DefaultAudioSink always supports floating point input. Make it
advertise this fact.
- Remove the ability to enable/disable floating point output in
FfmpegAudioRenderer, since this ability is now also provided on
DefaultAudioSink.
- Let FfmpegAudioRenderer query the sink to determine whether it
will output floating point PCM directly or resample it to 16-bit
PCM.

CSS background-color isn't inherited to inner HTML elements by default:
https://developer.mozilla.org/en-US/docs/Web/CSS/background-color
But Android Span styling assumes an outer BackgroundColorSpan will
affect inner spans. This usually doesn't make a difference, because
HTML elements are transparent by default, so there's an implicit
inheritance by just being able to see through to the 'outer' element
underneath. However this doesn't work if the inner element sits outside
the bounding box of the outer element, e.g. <rt> (ruby text, sits above/below)
or a <span> with font-size > 100%.

Previously, the automatically selected subtitle track
has not been marked (with check mark) in subtitle track list,
just like audio track.
But, in subtitle track option UI, there is no 'auto' option,
which is different from audio track selection menu.
This CL marks the auto selected subtitle track name in the cc list.

Sharing the Handler has led to it being accidentally used for purposes
beyond the original intention.
Instead for EPII -> EPI communication: Call methods directly on
ExoPlayerImpl that then post from the playback thread to the
application thread.
And for the MediaSourceList and Queue initialization, create a dedicated
Handler based on the same applicationLooper.

Also flip DefaultDrmSessionManager#prepare()/release() into guard
clauses.
