sys/glsink/gstvideo-common.*: Pull together some common raw video functions into one location.
Original commit message from CVS: * sys/glsink/gstvideo-common.c: * sys/glsink/gstvideo-common.h: Pull together some common raw video functions into one location. This should eventually move to -base. * sys/glsink/Makefile.am: * sys/glsink/glimagesink.c: * sys/glsink/glimagesink.h: * sys/glsink/glvideo.c: * sys/glsink/glvideo.h: * sys/glsink/gstopengl.c: Use the new video-common.h stuff. Readd support for RGB video.
