Sebastian Dröge a8f8d1b032 playback/player: player: Refactor video rendering API 
There's a GstPlayerVideoRenderer interface now, which defines how video
rendering happens in GstPlayer. Included is an implementation for the
GstVideoOverlay interface, and inside the GTK example application one for
gtksink/gtkglsink.
