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).

There's no reason to perform the discontinuity check or skip
the adaptation field if we don't have a payload reader for
the packet.

This fixes infinite loop in LeastRecentlyUsedCacheEvictor.evictCache when index store fails.

Also made CachedContentIndex not final so it can be mocked and added a package protected SimpleCache
constructor so mock index can be injected.

Very subtle, but lastAvailableSegmentNum is shifted by
RepresentationHolder.segmentNumShift. When accessing the
index directly it's necessary to unshift. The easiest way
to do this is to call through the holder, which does this
for you.

This case may happen if the max span size is more than the max size the
evictor is configured.

1- Avoid dropped buffers by using a PriorityQueue instead of a set.
2- Process the end of stream after non-EOS buffers.

1. Only tell sessions that want provisioning when provisioning occurs.
2. Also propagate failure to provision to these sessions.
3. If a session responsible for provisioning is released, start
   provisioning using another session instead.

- MediaDrmEventListener.onEvent is typically called on the
  app's main thread. mediaDrmHandler is instantiated on the
  playback thread. Hence mediaDrmHandler should be volatile
  to ensure visibility.
- Nulling mediaDrmHandler could result in a NPE in onEvent.
  Instantiate mediaDrmHandler (and don't null it again) to
  avoid this. MediaDrmHandler.handleMessage will correctly
  discard any events for sessions that are now closed.

AdsMediaSource lives in the core library so only ImaAdsLoader remains in
the ima extension. AdsMediaSource takes an AdsLoader implementation.

ImaAdsMediaSource is deprecated rather than removed for now.

This allows test runs to continue when the activity
is paused (but not stopped), which is in line with
what we do in the demo app's PlayerActivity.

Currently, to make transition to next media period seamless, after the renderer
has read until the end of the current SampleStream, we may send it the next
SampleStream so the renderer may read from the next SampleStream ahead of the
transition.
For NoSampleRenderer, we should avoid doing this: skipping ahead for such
renderer doesn't have any benefit (the renderer does not consume data from
SampleStream), and it will change the provided rendererOffsetUs while the
renderer is still rendering from the playing media period.

This allows listeners to easily determine the source of the discontinuity.
Reasons can be period transitions, seeks, and internal reasons.

Listeners still using the deprecated ExoPlayer.EventListener interface were
updated to Player.EventListener.
