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.

The only use of track selection factories is as adaptive track selection factories
in the DefaultTrackSelector. Using the fixed track selection factory here is dangerous
as it will throw if more than one track is selected.
