- If there's no program-date-time then this change is
  a no-op.
- If there is a program-date-time this change considers
  the period as having started at the epoch rather than
  at the start of the content. The window is then set
  to start at the start of the content. This is a little
  weird, but is required so that the period sample
  timestamps match the start of the period. Note that
  this also brings the handling of on-demand in line
  with how the live case is handled, meaning there wont
  be weird changes if a live stream changes into an
  on-demand one.

This has always been broken in V2, but the issue is now also
visible for the very first period in the timeline because we
offset if by 60s. Previously the issue would only have been
visible from the start of the second period.

Also clarify when getNextLoadPositionUs and continueLoading
can be called.

ClippingMediaSource wraps a single period/window video-on-demand source and
exposes a specified time range within it.

This is particularly problematic for subtitle tracks where adjustment
can be broken. Now, the primary url can change when clients ask for a
variant snapshot, instead of happening on chunk load as before.

Change Sink to Source in license header

Not sure what I think about this, but we're getting quite
a lot of issues reported where streams play fine but capabilities
indicate they wont. It's probably best just to cross our fingers
and hope for the best in such cases, as was the case in V1 when
using ExtractorSampleSource.

This requires knowing the seek time in Extractor.seek, so that it's possible to
pick the latest synchronization sample at/before the seek time for each track
(rather than the earliest synchronization sample after the seek position).

Also remove the STATE_AFTER_SEEK state which should no longer be needed.

When the primary url is blacklisted (due to a 404, for example) or
the selected variant is different from primary url, allow the tracker
to change the url.

Pending improvement:

* Peek just the required priv frame. Avoid decoding all id3 information.
* Sniff the used container format instead of using the extension.

The definition of negative line indices was intentionally shifted
by one because the way VTT defines them doesn't appear to allow for
cues to be positioned at the very bottom of the screen in the case
that ANCHOR_TYPE_END is used.

- Fix bug where we'd try and call replaceStream having already
  notified the renderer that the current stream is final. This
  could occur if a period was added to the end of the playlist.
- If the current period being played is removed and a new period
  to play cannot be resolved, assume we've gone off the end of
  the playlist and transition to the ended state. This allows
  the current source to be re-used (unlike the previous behavior
  of considering it an error). Treat valid seeks that cannot be
  resolved due to concurrent timeline update similarly.
- Add seek sanity check back to ExoPlayerImpl. Meh. It's probably
  best to keep this, since it stops the exposed window index
  being invalid w.r.t the exposed timeline.

- Infer likely left/center/right alignment for pop-on captions.
  This makes the rendering much better in practice, particularly
  when the captions were intended to be center aligned.
- Fix line anchoring.
