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].

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.

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.

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.

The method track(int id) currently has different behaviours across

TrackOutput instance. Also fixes TsExtractor inconsistent behavior

This CL adds support for initialization segments in HLS. This is required mainly for(but not limited to) usage of fMP4. The fMP4 support only consists in creating the required extractor if the extension is .mp4, provided the initialization segment is correctly

All of the classes in the text.eia608 package have been moved to
text.cea, and renamed with the "cea" prefix instead of "eia". All of
the buffering logic has been extracted from Cea608Decoder (formerly
Eia608Decoder) into the abstract CeaDecoder, which Cea608Decoder
extends. Cea608Decoder also now expects a 3-byte sample (i.e. the
entire cc_data_pkt instead of just the cc_data_1 and cc_data_2 bytes).
Classes like RawCcExtractor and SeiReader, responsible for creating
these samples, have also been updated accordingly.
This change is a necessary precursor to adding support for multi
-channel CEA-608 and CEA-708 captions.

HlsSampleStreamWrapper and ExtractorMediaPeriod would call
onPrepared/onSourceInfoRefreshed from their loading threads. That was
problematic for ConcatenatingMediaSource and MergingMediaSource, which assume
that their callbacks are called on the same thread (iterating through timelines
from all sources and updating pendingTimelineSources respectively). This change
makes them post calls to the callbacks on the playback thread.
Generally, implementing a composite MediaSource is easier if
MediaPeriod.Callback's methods are all called on the same (playback) thread, so
this change makes that part of its contract.
Also post onContinueLoadingRequested from ExtractingLoadable because
MergingMediaPeriod.onContinueLoadingRequested reads trackGroups written on the
playback thread.

If the live window has a small duration, we currently
end up setting the default start position to be right
at the start of the window. This increases the chance
of a BehindLiveWindowException.
With this change we impose a minimum 5s gap between
the start of the window and the default start position.
If the window is *really* small (<10s) then doing this
would push the default start position too close to the
end of the window. We don't have much time to play with
in either direction in this case, so we put the default
start position in the middle of the window and hope for
the best.

Now you can do cool things (if you really want to!) like
play a video twice, then play a second video, then loop
the whole thing, all seamlessly.
new LoopingMediaSource(
new LoopingMediaSource(firstVideoSource, 2),

You can also just loop, which is probably more useful :).
