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

this value is not set correctly.

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.

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.

SectionPayloadReaders are provided to a SectionReader to
get whole sections(crc checked). This allows the injection
of custom section readers. E.G: SCTE35 messages.

In this CL:
* PesReader moves out of TsExtractor and becomes public.
* ElementaryStreamReaderFactory becomes TsPayloadReaderFactory and is
moved to TsPayloadReader.
* The TsPayloadReaderFactory is in charge of wrapping any
ElementaryStreamReaders with a PesReader.
Incoming:
* Extract SectionReader supperclass (analog to PesReader, but for
sections) from Pat and Pmt readers.
* Add a ScteReader, wrapped by a section reader, and include it in
the DefaultTsPayloadReaderFactory.

pesPayloadReader can be null here because DefaultStreamReader.init() can return null on unknown streamId. If we have a junk transport stream in our content an exception will be thrown.
*** Reason for rollback ***
Flag doesn't enforce what it says it enforces, due to redirects
*** Original change description ***
Add REQUIRE_HTTPS flag
Note that it's not possible for the library to enforce that
the flag is adhered to, since it's possible for applications
to inject custom implementations of DataSource (there's no
requirement they even extend HttpDataSource for network
requesting implementations). It's possible for applications
to replace pretty much anything in the library, so there's
no other place we could put the flag where we could make
this guarantee. Hence this is a best-effort that will work
when...

This is a problem when two invocations of getNextChunk that retrieve
chunks (i.e. not playlists) occur too apart in time. In that case
the last loaded chunk has a media sequence that is behind the current
playlist.
