Niklas Haas 5e50a56b9c swscale: add new frame testing API 
Replacing the old sws_isSupported* API with a more consistent family
of functions that follows the same signature and naming convention,
including a placeholder for testing the color space parameters that
we don't currently implement conversions for.

These functions also perform some extra basic sanity checking.
