If we prepare a deferred media period before the actual timeline is available,
we either prepare with position zero (= the default) or with a non-zero
initial seek position.
So far, the zero (default) position got replaced by the actual default position
(including any potential non-zero window offset) when the timeline became known.
However, a non-zero initial seek position was not corrected by the non-zero
window offset. This is fixed by this change.
Related to that, we always assumed that the deferred media period will the
first period in the actual timeline. This is not true if we prepare with an
offset (either because of an initial seek position or because of a default
window position). So, we also determine the actual first period when the
timeline becomes known.

These two methods are meant to indicate to the track selection that it's
started or stopped being used. This is helpful to schedule background tasks
related to track selection (e.g. register network change listeners etc.).
This intention is not clearly stated in the method docs.
Also, all track selections of all prebuffered periods stay enabled in
parallel at the moment. As the whole purpose of these methods is to know
whether dynamic updates via updateSelectedTrack may happen, it's better to
only enable track selections of the current loading media period. That's
similar to how we always forward the loading track selections to the
LoadControl.
This change:
1. Improves the JavaDoc of TrackSelection.
2. Disables track selections if loading moves to another period.
3. Reenables track selection if loading moves back to a previous period.

Extend Sony workaround up to and including Oreo.
Due to a platform issue the Display API couldn't report 1080p UI
and 4k SurfaceView support until Oreo. Since Oreo it is still
common for devices to misreport their display sizes via Display,
so this change switches to using system properties up to and
including Pie.
On Pie treble may prevent writing sys.display-size so check for
vendor.display-size instead.

If a source is removed from the playlist, the player may still call createPeriod
for a period of the removed source as long as the new timeline hasn't been handled
by the player. These events are stale and can be ignored by using a dummy media
source. The stale media period will be released when the player handles the updated
timeline.

This method needs to be called whenever the track selection of the current
loading period changes, but also when the loading period itself (and thus
the "loading track selection") changes. These are the same situations in which
we update the loading media period id and thus we can move both updates in
a common helper method.

From API 23 this uses the timed format queue. Before API 23 the
format is notified as soon as the buffer is queued.

Before this change we would reset the start trim to zero after initial
configuration (at the start of playback) and after seeking to any position. The
fact that no trimming was applied at the start of playback meant that after the
first period transition we'd see a mismatch between the next buffer timestamp
(equal to the duration of the period taking into account edits) and the duration
of audio submitted to the sink.
This change modifies the behavior so that we reset the start trim to zero only
if some audio was queued since configuration. This is incorrect in the case of
starting playback at a non-zero position, but fixes the common case of starting
at zero. As before, a later seek to any position is handled via a flush and
resets the trim as required.
Transitions from one period to the next are unaffected by this change.
One way to implement start trimming correctly would be to provide the input
buffer timestamp to the audio processors and only trim when handling audio from
the start of the stream, but that is a larger change so left for later.

After a period transition the first buffer queued has the sum of previous period
durations added to its source presentation timestamp. These durations take into
account gapless edits, but the check on the timestamp was based on the submitted
frame count, not the frame count after trimming.
This change fixes an issue where audio/video would gradually drift apart due to
accumulated error in the audio track position, which could lead to freezing due
to the audio renderer stopping being ready and switching to the standalone media
clock.
