SwitchCallback

A callback into the Player that should be called when the AbrManager decides it's time to change to a different variant. The first argument is a variant to switch to. The second argument is an optional boolean. If true, all data will be removed from the buffer, which will result in a buffering event. Unless a third argument is passed. The third argument in an optional number that specifies how much data (in seconds) should be retained when clearing the buffer. This can help achieve a fast switch that doesn't involve a buffering event. A minimum of two video segments should always be kept buffered to avoid temporary hiccups.
