SDK / exoplayer

This methods allows to replace single items or a range of items directly
without using separate operations for add and remove. The advantage is
more readable code for apps and the potential for player
implementations to optimize this process (e.g. only replace values
without interrupting playback).

The current change just introduces the API with its default behavior.
The default logic will be removed again in the future in favor of
better logic in the Player implementations.
