video_output/opengllayer.m:

* Code simplification. Green flashes removal. Call display instead of setNeedsDisplay: to make sure we have a frame per fram
e accuracy. Use removeVoutLayer: to detach the drawer from its drawable.
MacOSX/Framework:
* Code factorization from VLCVideoView, VLCVideoLayer in VLCVideoCommon
* Implement removeVoutLayer: as needed by the opengllayer.
