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.

This allows to use a fake clock and an action schedule with timed delays
together.

The default implementation is just calling through to handler.postDelayed,
while the fake clock uses its internal time value to trigger the handler
calls at the correct time.

This is useful to apply a fake clock in situations where a handler is used to
post delayed messages.

In order to retrieve the data set, the track selection index was used, but
the data set is actually indexed by track group indices.

Currently FlacDecoder/FlacExtractor always perform resampling to 16bit. In some
case (with 24bit audio), this might lower the audio quality if the system
supports 24bit audio.
Since AudioTrack implementation supports resampling, we will remove the
resampling step, and return an output with the same bits-per-sample as the original stream.
User can choose to re-sample to 16bit in AudioTrack if necessary.

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

The bytesRemaining didn't always take into account any skipped bytes, which
meant that reaching the end of the file was not correctly detected in read().

UTF-8 is the default charset on Android so this should be a no-op change, but
makes the code portable (in case it runs on another platform).

*** Reason for rollback ***

Doesn't work because trackOutputProvider can be null when extracting init data.

*** Original change description ***

Don't copy primary-track format to non-primary tracks

Copying non-primary-track formats to non-primary tracks
looks non-trivial (I tried; went down a dead-end), so
leaving that for now.
