Remove the strange things the old mp_image_setfmt() code did to the image format parameters. This includes setting chroma shift to 31 for gray (Y8) formats and more. Y8 + vo_opengl_old didn't actually work for unknown reasons (regression in this branch). Fix this. The difference is that Y8 is now interpreted as gray RGB (LUMINANCE texture) instead of involving YUV (and levels) conversion. Get rid of distinguishing RGB and BGR. There wasn't really any good reason for this. Remove mp_get_chroma_shift() and IMGFMT_IS_YUVP16*(). mp_imgfmt_desc gives the same information and more.
