Refactor: Change the position of variable.

Add support for AVC Level 5.2

*** Reason for rollback ***

This change may silently introduce bugs where both parameters are acceptable in both places. It's decided that the gain isn't worth the risk.

*** Original change description ***

Make the error messages the first parameter in Assertions methods to match JUnit methods

Reverse parameter order creates a slight confusion.

source of the current CronetEngine.

Added test to ExoPlayerTest which changes the repeat mode during playback.
Test verifies that ExoPlayer shows the periods in the intended order.

- Call onDisabled last. onDisabled really shouldn't be doing
  anything with the stream, so pretty sure this is fine (and
  guarantees the stream is cleared properly even if onDisabled
  throws a RTE).
- Remove super.onDisabled calls from Text/Metadata renderers.
  This is just for consistency; we don't make such calls in
  other direct descendants of BaseRenderer.

If a timeline update removed periods at the end of the timeline which
had been buffered, handleSourceInfoRefreshed would call
getNextPeriodIndex and get back -1 for the last period holder in the
new timeline. Then isLastPeriod(-1) could throw.

Fix this behavior so that the remainder of the timeline is discarded.

Changing the repeat mode during playback may require to discard or rebuffer
certain periods because the requested order of playback changed.

The Timeline base class provides the default implementation.

Timeline wrappers (e.g. ClippingTimeline, ConcatatedTimeline) forward all
requests to the respective inner timelines. Some like ConcatenatedTimeline add
their own additional logic to bridge between the child timelines.

In addition, ConcatenatedTimeline and LoopingTimeline now have a common
abstract base class as they share most of their code.

Even though this is not strictly spec compliant, this will make exoplayer
behave like it used to before multiple program support. Developers
who want to take advantage of the multiple program support are probably
less than the ones who only want their stream to "just work". This is
particularly useful for streams obtained after a filtering component,
like a tv tuner.
