SDK / exoplayer

This test is not run in presubmit as it was too flaky, and is currently broken
due to assets moving.

Also migrate off ImaPlaybackTest off deprecated APIs.

1. Move logic to decide to re-initialize the codec rather than using
   MediaCodec.setMediaDrmSession if (a) PlayReady is in use, and (b)
   the new session is still provisioning. This would previously have
   happened asynchronously after an input format change, after the
   decoder has subsequently been flushed. After this change the logic
   executes synchronously when the input format changes. This helps
   with the ref'd bug, since we want to propagate reasons for codec
   re-initialization through inputFormatChanged events.
2. Whilst moving the logic for re-initialization if PlayReady is
   being used, I fixed a bug that would occur when switching from
   [PlayReady --> non-PlayReady]. Re-use doesn't work in this case.
   The old logic only checked for the [Something --> PlayReady] case.
3. Remove pointless codec flush if updating the DRM session having
   not queued anything to the codec.

- I don't think the session recovering later would work, because
  the codec will be configured not to use it.
- I'm not sure session recovery makes sense in general, and our
  implementations do not do this. Document it as a terminal state
  for now.

This avoids confusion that currently exists between "operating rate"
and "codec operating rate", which are different. It also tightens the
requirement of the value being passed to be more than a "hint". It's
already being used as more than a hint for setting the Surface frame
rate.

Some content types always provide the license URL in the media.
The PlayReady example in the demo app doesn't provide a default
license URL for this reason, as an example.

In a later change ImaAdsLoader will use multiple AdTagLoaders.

This change shouldn't have any substantial changes in behavior (it's almost
entirely moving code around). An exception is that ImaSdkSettings is configured
when making a request rather than at construction time.

This change will be followed up by:
- Changes adding APIs to enable the use of MediaParser in each of the supported
  media sources.
- Changes removing TODOs related to the change of the stable SDK to API 30.

In order to ensure we can update the values for new manifests but still use
the user provided override, we need to save the original and the updated MediaItem
seperately.

And in order to incorporate the existing logic for the min/max supported live
offset, which we already use to correct the target offset, also move both places
together so that all the adjustment happens in one place.

Logical adjustments to the previous min/max supported live offset:
 - Use the user-provided MediaItem values if set
 - Use the newly parsed ServiceDescription values if available.
 - Limit the minimum to 0 if the current time is in the window and we can
   assume to have low-latency stream.
 - Add minBufferTime from the manifest to ensure we don't reduce the live
   offset below this value.

ExoHostedTest was calculating the total play time by solely listening
to onIsPlayingChanged. The last update to false (when playback ends) was relying
on a callback that was always called after the player has already been released.
This happened because of a now fixed bug where callbacks were still issued if
player.release() is called from within another callback (as in ExoHostedTest).

Fix the currently broken test by posting the release call so that all pending
events are still delivered first.

ImaAdsLoader notified onEnded whenever an ad finished playing, but when an ad
is skipped in an ad pod we'd receive a playAd call before the player
discontinuity for skipping to the next ad. Fix this behavior by checking that
IMA's playing ad matches the player's playing ad before notifying onEnded.

This allows the user and the media to define bounds in which the live offset
can vary.

Logic for determining if (and how) decoders can be adapted is
currently split between renderers and MediaCodecInfo. This change
centralizes the majority of the logic in MediaCodecInfo.

This change also fixes a bug in MediaCodecAudioRenderer when computing
max values for the codec. Previously, max values would not be increased
to account for potential adaptation to another stream in the case that
the codec needs to be flushed for the adaptation to occur.
