Original commit message from CVS: * sys/osxvideo/cocoawindow.h: * sys/osxvideo/cocoawindow.m: * sys/osxvideo/osxvideosink.h: * sys/osxvideo/osxvideosink.m: Disable the cocoa event loop since it's a huge memory leak. Should only matter if the sink isn't used within an NSApp (which has already got a coca event loop). Remove all unused code.
