Commit 4f566363 by tonihei Committed by Oliver Woodman
Options

Add window index and media period id to media source event listener events. 

This allows to distinguish between media source events of multi-window and
multi-period media sources. In this change, only media sources currently reporting
events are changed. Proper support in composite sources will be added in a later
change.
