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

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].

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.

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.

The method track(int id) currently has different behaviours across
implementations. This CL maps ids to track outputs, which means
that successive calls with the same id will return the same
TrackOutput instance. Also fixes TsExtractor inconsistent behavior
after a seek.

This allows the injectable reader factory to be a stateless factory, allows
the seeking to be consistent and will allow multiple CC channel support later
on.

- Lots of misc cleanup
- Remove GaplessInfo from Metadata. IMO it doesn't quite belong there,
and means it ends up being represented twice inside Format.
- Note: Changes untested, but will be tested in due course!
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
loaded and passed to the extractor.

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.

Make FakeExtractorInput's end of input detection to apply also for peekFully, and

Adds a few unused fields to HlsUrl and moves things towards the Hls
reimplementation we are looking for. Also fixes a bug related to
asuming every getNextChunk().loadable == null being related to
reaching the live edge.

- Centralise compileSdkVersion, targetSdkVersion and
buildToolsVersion in a single place for gradle.
- Bump compileSdkVersion and targetSdkVersion to 24.
- Bump com.android.tools.build version to re-enable
instant start.
- Bump targetSdkVersion in manifests (needed for
internal builds).
- Use standard expandable_list_item from Android in
the demo app, since ours doesn't look right when
targeting API level 24. We were also setting the
theme on the wrong element in the manifest, so I'm
removing that line.

- Use a single constant for unset/unknown times across
all time bases. Note also that this moves away from
use of -1 for unset/unknown times in ms, which was a
bad choice (it might conflict with real times, such
as a time representing being just behind the start
of a live window).
- Add a few other unset constants, and use them.
- Fix some hardcoding of -1 where existing constants
should have been used.

The classes these tests are written for have changed
so much we'll have to write them again. We can refer
to V1 if we want to look at what the old tests did, so
there's no need to keep this file in the V2 tree at
the moment.

SmoothStreaming -> Ss
MediaPresentationDescription -> DashManifest
DashSingleSegmentIndex -> SingleSegmentIndex
Moved DASH and Ss manifest classes to matching
manifest packages for consistency. For Hls the
package is called playlist still, since that's
what they're widely known as.
