This allows to distinguish between media source events of multi-window and
multi-period media sources. In this change, only media sources currently reporting
events are changed. Proper support in composite sources will be added in a later
change.

This is achieved by moving the listener registration and the creation of the
event dispatcher into BaseMediaSource.

Before this change, HlsMediaSource timelines had a period starting at the epoch.
For VOD streams the window position in the period was the program date time.
This change makes period and initial window positions match. For live streams
the window position advances as segments are removed, so its position in the
period is the difference between the initial program date time and the program
date time of the latest playlist.
This also makes it possible to insert ads in VOD HLS content with program date
time, as the period and window are now aligned.

- Change 'compile' configuration (deprecared) to using 'implementation'
and 'api' configurations instead.

This is achieved by adding a BaseMediaSource which keeps a reference count of the
number of times the source has been prepared and forwards to the actual implementations
only once, such that only minimal changes are needed for each media source.

Releasing the player released the internal playback thread once renderers were
released. Releasing a MediaPeriod queued a Loader.ReleaseTask on the loading
thread which would post back to the playback thread. If the playback thread had
been quit by the time this happened, the release task wouldn't be run.
Release on the loading thread instead of the playback thread. This avoids
needing to block releasing the player until the loading threads have ended, and
ensures that release tasks will run eventually. As part of this change,
ExtractorMediaPeriod's call to Extractor.release will now run on the loading
thread (which means that all Extractor methods are called on that thread) and
other cleanup in ReleaseCallback will run on the loading thread instead of the
playback thread.

This achieves two things:
1. All our tests use the same type of assertions.
2. The tests currently run as instrumentation test can be moved to
Robolectric without changing the assertions.

This solves the problem of having dense tracks' ids change.
For example, if the available variants offer both HEVC and AVC video
tracks, all video samples will map to the same sample queue even if
IDs don't match.

If allowed, the media period will try to finish preparation without downloading
chunks (similar to what DashMediaPeriod does). To create track groups,
HlsMediaPeriod will try to obtain as much information as possible from the
master playlist. If any vital information is missing for specific urls,
traditional preparation will take place instead.
This version does not support tracks with DrmInitData info. This affects tracks
with CDM DRM (e.g: Widevine, Clearkey, etc). AES_128 encryption is not affected.
This information needs to be obtained from media playlists, and this version
only takes the master playlist into account for preparation.

In some occasions, we may want to discard a part of the buffered media to
improve playback quality. This CL adds this functionality by allowing the
loading media period to re-evaluate its buffer periodically (every 2s) and discard
chunks as it needs.

In order to facilitate enabling a compile-time error check, we are suppressing these existing instances. Once the compile-time error is enabled, we will file bugs to clean up any unfixed instances in [].
Note that this CL should result in no effective changes to the code, but the code as currently-written might contain a real bug. If you'd prefer to fix the bug now, please either reply with edits, or accept this CL then follow up with a change that fixes the underlying issue.
Tested:

We've found that in our production environment, the AAC stream's timestamp exceeds the 33bit limit from time to time, when it happens, `peekId3PrivTimestamp` returns a value that is greater than `TimestampAdjuster.MAX_PTS_PLUS_ONE`, which causes a overflow in `TimestampAdjuster.adjustTsTimestamp` (overflow inside `ptsToUs`) after playing for a while . When the overflow happens, the start time of the stream becomes negative and the playback simply stucks at buffering forever.
I fully understand that the 33bit is a spec requirement, thus I asked our stream provider to correct this mistake. But in the mean time, I'd also like ExoPlayer to handle this situation more error tolerance, as in other platforms (iOS, browsers) we see more tolerance behavior.
Also prevent skip when there's a pending reset, and add a
TODO to split/fix chunk discard and downstream format change
reporting.

Currently for a DASH ChunkSource that consists of multiple sub-streams, we
always use a CompositeSequenceableLoader, which only allows the furthest behind
loader or any loader that are behind current playback position to continue
loading.
This changes allow clients to have more flexibility when deciding the loading
strategy:
- They can construct a different kind of composite SequenceableLoader from
the sub-loaders, and use it by injecting a different CompositeSequeableLoaderFactory accordingly.

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.
