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.

Remove gapless functionality that relies on MediaCodec, and implement this in
an AudioProcessor instead.

Currently our Renderer is always associated with and consume data from
some SampleStreams, which were constructed from the provided MediaSource.
There are use-cases, in which the users want to have simple Renderer
implementation that does not consume data from SampleStream at all, but
render using their custom logic at each rendering position - they mostly just
need ExoPlayer to keep track of the playback position and enable/disable the
renderer.
This CL adds support for such Renderer by adding a TRACK_TYPE_NONE.
Renderer of such type will be:
- Associated with null TrackSelection as the result of track-selection
operation.
- Associated with EmptySampleStream.

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.

The sleep used to simulate data load times is ignoring InterruptedExceptions.
(This is intended and in line with SystemClock.sleep()). However, when a
Loader cancels an ongoing load, it uses interrupts. To be able to catch these
and to immediately return from the reading data source, a handler callback
is used instead of the sleep() method which allows interuptable waiting.

When having a repeat() action and another subsequent action,
the next action should only be scheduled once (and not repeatedly).
Thus, the "next" pointer in the repeated action needs to be nulled
in the first iteration to prevent repeated scheduling of the next action.

Releasing the media period should also release the sample streams
to allow resources to be cleaned up.

The release callback handler in Loader might not be alive
anymore. Catch this case to prevent warnings about sending
messages on dead threads.

This simulates reading from the buffer (which is what actual
renderers would do). Otherwise the buffer always gets expanded
and might cause memory issues.

In this case the playback state transitions to IDLE, which isn't
caught so far. (This code is equivalent to the one in ExoHostedTest.java)

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.

Everything should go through the ExoMediaDrm layer. We still
need to abstract away the android.media exception classes, but
this is left as future work.

This appears to be fixed in Oreo, but given how harmless
the workaround is we can probably just apply it on all
API levels to be sure.

Reporting incorrect positions for ad playbacks was causing IMA to
think the ad wasn't playing, when in fact it was.

Also pass an unresolved end point to ClippingMediaPeriod. This removes some
assertions checking timestamps in the ClippingMediaPeriod, but makes it
possible to identify when the end point is at the end of the media.

When creating PlaybackControlView inside SimpleExoPlayerView,
we want certain attributes to be passed through. This lets you
set control attributes on the SimpleExoPlayerView directly. We
don't want all attributes to be propagated though; only our own
custom ones.

Not sure if there's a cleaner way to do this. Pragmatically this
solution seems ... ok :)?

Spec: https://storage.googleapis.com/wvdocs/Widevine_DRM_Android_Using_Key_Rotation.pdf

1. Implement multisession to support drm key rotation
2. Put MediaDrmEventListener back to manager since this is a per mediaDrm thing.
3. It seems diffrenciate between single/multi session is unnecessary.
