The filter chain and the video ouputs have config() functions. They are strictly limited to transfering the video size and format. Other parameters (like color levels) have to be transferred separately. Improve upon this by introducing a separate set of reconfig() functions, which use mp_image_params to carry format parameters. This struct contains all image format related parameters from config(), plus additional parameters such as colorspace. Change vf_rotate to use it, as well as vo_opengl. vf_rotate is just an example/test case, but vo_opengl will need it later. The intention is also to get rid of VOCTRL_SET_YUV_COLORSPACE. This information is now handed to the VOs via reconfig(). The getter, VOCTRL_GET_YUV_COLORSPACE, will still be needed though.
