InternalErrorListener (library API)

```
public interface InternalErrorListener
```
A listener for internal errors.
These errors are not visible to the user, and hence this listener is provided for informational purposes only. Note however that an internal error may cause a fatal error if the player fails to recover. If this happens, ExoPlayerListener.onError(ExoMediaPlayer, Exception) will be invoked.
