For live streaming, there are several types of DASH `emsg' events that directly
target the player. These events can signal whether the manifest is expired, or
the live streaming has ended, and should be handle directly within the player.

DASH manifests can now contain non-null but incomplete
DRM init data. Hence using the manifest init data when
non-null is not always the correct thing to do. This
change merges the sample and manifest formats (which
correctly merges the DRM init data) and then uses the
result.

- Parse multiple kids from default_KID. It's specified as a whitespace
separated list of UUIDs rather than a single UUID.
- Opportunistically proceed with playback in cases where the manifest
only defines a single SchemeData with the common PSSH UUID. In such
cases the manifest isn't saying anything about which specific DRM
schemes it supports.

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.

Currently EventMessage's presentationTimeMs is kept separately in
EventSampleStream. However, EventMessage's presentationTimeMs maybe used in
other places besides EventSampleStream, such as when handling `emsg' messages
targeting the player. This CL let EventMessage object to holds its
presentationTimeMs for such use cases.

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.

MPD file may include multiple EventStreams in its Periods, which contains Events
that the application may need to handle/respond to.
This change adds support for parsing the EventStream/Event nodes from MPD
file, and exposing these EventStreams as a metadata sample stream that application
can respond in a similar way to other metadata events.

- 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.

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).

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.

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.

Remaining instrumentation tests either use android.os.Handler or rely on assets.
In the latter case, the tests are difficult to migrate due to differences
between the internal and external build systems, and configuration needed in
Android Studio. In addition, SimpleCacheSpanTest remains as an instrumentation
test because it fails due to a problem with string encoding on the internal
build (and two other tests in its package are kept with it because they depend
on it).
This test removes a dependency from testutils on Mockito, as a different
version of Mockito needs to be used for instrumentation tests vs Robolectric
tests, yet both sets of tests need to rely on testutils. Mockito setup is now
done directly in the tests that need it.
Move OggTestData to testutils so it can be used from both instrumentation and
Robolectric tests.
It may be possible to simplify assertions further using Truth but this is left
for possible later changes.
