Original commit message from CVS: * gst/deinterlace2/tvtime/greedyh.asm: * gst/deinterlace2/tvtime/greedyh.c: (greedyDScaler_C), (deinterlace_frame_di_greedyh), (dscaler_greedyh_get_method): * gst/deinterlace2/tvtime/greedyhmacros.h: Add a C implementation for the greedyh deinterlacing method, clean up the code a bit and mark the SSE version as MMXEXT as it doesn't require any SSE instructions.
