These variables are never read, since the underlying control
view reads them directly from the attrs.

This fixes VOD->Live transitions, with the caveat that
the Live portion still ends up further behind the live
edge than intended. This will be fixed in a following
change.

This change fixes the race condition where the internal
timeline is different to the externally visible timeline
when a seek is performed. We now resolve the seek position
using the externally visible timeline, then adjust the
period index as required for the internal timeline. If the
period is missing we follow similar logic for the existing
case where the playing period is removed.

This CL adds a SpliceInfoDecoder for the most common SCTE35 commands for splcing.
So far, it only includes TransportStreams, but porting it to HLS and DASH should be
fairly easy.

This is the first step towards allowing discontinuities in the
playlist tracking. Also changed durationSecs for durationUs in
MediaPlaylist.Segment.

A VOD-style period in a dynamic manifest would result in a NullPointerException.
Also fix another issue in which an unrecognized mime type would also result in
NullPointerException.

In order to expose the live window, it is necessary (unlike before) to refresh
the live playlists being played periodically so as to know where the user can
seek to. For this, the HlsPlaylistTracker is added, which is basically a map
from HlsUrl's to playlist. One of the playlists involved in the playback will
be chosen to define the live window. The playlist tracker it periodically.
The rest of the playilst will be loaded lazily. N.B: This means that for VOD,
playlists are not refreshed at all. There are three important features missing
in this CL(that will be added in later CLs):

* Blacklisting HlsUrls that point to resources that return 4xx response codes.
    As per [Internal: b/18948961].
* Allow loaded chunks to feed timestamps back to the tracker, to fix any
    drifting in live playlists.
* Dinamically choose the HlsUrl that points to the playlist that defines the
    live window.

Other features:
--------------

The tracker can also be used for keeping track of discontinuities. In the case
of single variant playlists, this is particularly useful. Might also work if
there is a that the live playlists are aligned (but this is more like working
around the issue, than actually solving it). For this, see [Internal: b/32166568]
and [Internal: b/28985320].

- Use A/V tracks only for buffering position when available
  in ExtractorMediaPeriod.
- Fix layering of exo_simple_player_view so that subtitles
  are above album art. The test stream provided has both.
- Make album art in SimpleExoPlayer view respect the resize
  mode, like we do for video.

Merge ID3 support into dev-v2

TrackSelector no longer has a listener. Instead, tracks
change events are reported through ExoPlayer.EventListener.
Applications interested in retrieving the selection info
should retrieve it directly from the TrackSelector by
calling an exposed getter.

Pretty sure the ref'd issue is fixed as a side effect of
this change.

Unlike with PesReaders, sections don't have a standard way
of providing timestmaps or even generating tracks. We need
to pass this information so that readers decide what to do
with it.

like SDT, EIT, CAT, etc.
