When SubtitlePainter positions the cues centred in the given box, it must add
the left offset of the box to get the correct position.

SubtitleView forwards the cue box position to SubtitlePainter. This should be
the position relative to the canvas of the SubtitleView. Currently, however,
we forward the position relative to the parent of SubtitleView. That causes
problems if SubtitleView has a non-zero offset position to its parent.

A lot of methods just forward to other methods and there is no conceivable
way a player should implement it another way. Moving these methods to a
base player class allows to remove duplicated code across our player
implementations.

For example, using ExoPlayer.STATE_IDLE falls back to the Player.STATE_IDLE
automatically and thus there is no need to keep the deprecated members.

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.

This allows selectAudioTrack() to be overridden.

More specifically, if the parts of the Format that are used
for decoder configuration are unchanged.

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.
