* introducing dct248 into the DSP context.
* simple/accurate implementation of dct248 * DV encoding now supports 2-4-8 DCT * DV encoding gets a bit faster (but still miles away from what I think it could do) * misc. DV codec cleanups Originally committed as revision 2425 to svn://svn.ffmpeg.org/ffmpeg/trunk
