Some Player methods like getting the Looper and adding listeners were always allowed to be called from any thread, but this is undocumented. This change makes the threading rules of these methods more explicit. Removing listeners was never meant to be called from another thread and we also don't support it safely because final callbacks may be triggered from the wrong thread. To find potential issues, we can assert the correct thread when releasing listeners. Finally, there is a potential race condition when calling addListener from a different thread at the same time as release, which may lead to a registered listener that could receive callbacks after the player is released.
