The attached patch adds swscale support for the YUVJ formats by properly
(I hope :) setting srcRange and dstRange in sws_setColorspaceDetails().

I verified that after applying the patch sws_getContext() does not fail
when asked to convert from/to YUVJ formats, and that it does not
segfault, but I do not know how to check if the conversion is right (I
cannot see the difference between YUV420P and YUVJ420P :). Maybe someone
more skilled than me can check if the conversion is done properly.
