This is a step toward retaining a back-buffer in a way that
works for all MediaSource implementations. It's not possible
to adjust the discardBuffer calls in ExoPlayerImplInternal
to discard up to (position - backBufferDurationUs). Next steps
are to:
1. Find an appropriate place to specify the back buffer value,
to be passed to the discardBuffer calls. I guess the
LoadControl is the appropriate place to define such values.
2. Enhance discardBuffer to support a toKeyframe argument to
pass through to discardTo.

Also did a bit a tidying up in HlsSampleStreamWrappen and
HlsMasterPlaylistParserTest.

- When transitioning to a new period, the value of bufferedDurationUs
passed to TrackSelection.updateSelectedTrack was incorrectly set to
0. It should have been set to correctly reflect buffered media in
previous periods still being played out.
- This change fixes the issue described above, and also propagates the
playback position through to this method. The position of the next
load within the period can be calculated by adding the position and
bufferedDurationUs.

Also create helper method in HlsMasterPlaylist to allow the copying of
the playlist to another, but with the variants reordered based on a
passed comparator. Also added an implementation of HlsPlaylistParser
which will reorder the variants returned.
Follow-up on the update to ABR logic in AdaptiveTrackSelection for live
streaming case:
- Do not reset liveEdgeTimeUs when user seek to a different position.
- For HlsChunkSource, for non-independent segments, currently the
bufferedDuration calculate will subtract previousChunk's duration. So to make
it work with live-streaming ABR logic, we subtract timeToLiveEdgeUs a similar
amount to compensate for that operation.
- Minor update to DefaultSSChunkSource, only perform TrackSelection when needed
(after checking necessary conditions).

In live streaming, if the playback position is very close to live edge,
the buffered duration will never reach minDurationForQualityIncreaseMs,
which prevents switching from ever happening. So we will provide the
durationToLiveEdgeUs to AdaptiveTrackSelection in live streaming case,
so it can handle this edge case.

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

This parameter is used by methods such as getNextWindowIndex
and getPreviousWindowIndex to determine the playback order.
Additionally, there are method to query the first and last
window index given the shuffle mode.
None of the timeline implementations nor the ExoPlayer
implementation supports shuffling so far.

Also add sample streams that use METHOD=SAMPLE-AES. Note that some of
the streams provide alternative EXT-X-KEY's. Support for alternative
decryption methods will be added in a later CL.

When resetting a SampleQueue, by default the upstream format
is not cleared. This is necessary for progressive playbacks,
since (a) the formats never change, and (b) the extractors
only output them once. So when a seek occurs, it's necessary
to clear all sample data from the queue, but retain the current
upstream format.
Uniquely for HLS, the media in a SampleQueue that we may read
from can be in a format not supported by the consuming renderers.
We clear all the sample data from the queue in this case, but
not the upstream format. Since we have an optimization that
allows the upstream format to be read in advance of another
sample being written into the queue, this can result in an
unsupported format being read by a consuming renderer. This
change ensures the upstream format is correctly cleared in the
problematic case.

This CL aims that the player fails upon:
- Playlist that don't change in a suspiciously long time,
which might mean there are server side issues.
- Playlist with a media sequence lower that its last snapshot
and no overlapping segments.
This two error conditions are propagated through the renderer,
but not through MediaSource#maybeThrowSourceInfoRefreshError.

This prevents ExoPlayer from thinking there are many more video tracks
than there actually are. And will prevent downloading multiple times
the same rendition once offline support for HLS is added.

With this change, it becomes possible to depend on ExoPlayer
locally in settings.gradle by doing:
gradle.ext.exoplayerRoot = 'path/to/exoplayer/root'
apply from: new File(gradle.ext.exoplayerRoot, 'core_settings.gradle')
You can optionally add a prefix onto ExoPlayer's module names
by adding:
gradle.ext.exoplayerModulePrefix = 'prefix'

It's currently difficult to use ExoPlayer modules in other gradle
projects because they rely on constants and dependencies defined
in our own top level gradle file. This change moves the constants
into a separate file referenced directly from each module. It also
removes the need for the top level gradle file to declare a
dependency on com.novoda:bintray-release. This is now only needed
if "exoplayerPublishEnabled = true" is specified.
