ad5f812c91 qroverlay: Rework basing it on overlaycomposition 
The base class is now a bin which wraps the `overlaycomposition`
element and implements the `draw` signal.

This way we support all the video formats the GstVideoOverlayComposition
API supports and the blending code can be reused. It is also possible
to have the blending happen in the sinks now.

This moves `gstqroverlay.c` to `gstdebugqroverlay.c` and implements
a simple `gstqroverlay` element.
