Currently SDL2 is not building in Linux (x86 and ARM), Android and MingW because include stdint.h has been removed from yuv_rgb.h

Updated SDL's YUV support, many thanks to Adrien Descamps
...
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.
