This adds a function pointer for forward MDCT to FFTContext and initialises it with the existing C function. ff_calc_mdct() is changed to an inline function calling the selected version as done for other fft/mdct functions. Originally committed as revision 19818 to svn://svn.ffmpeg.org/ffmpeg/trunk
