* Make the game vsync toggle work dynamically again
* Unregister producer's Binder object when closing layer
* Address ripinperi's comments
* Add a timeout on syncpoint wait operation
Syncpoint aren't supposed to be waited on for more than a second.
This effectively workaround issues caused by not having a channel
scheduling in place yet.
PS: Also introduce Android WaitForever warning about fence being not
signaled for 3s
