Plain C I420 to 2VUY conversion function.

See http://developer.apple.com/quicktime/icefloe/dispatch019.html for a complete description of 2VUY and fourcc.org for YUV 4:2:0.

2vuy is a like a 8-bit per component YUV 4:2:2, but it's actually a Y'Cb'Cr sampling. 2vuy is packed with bytes [Cb, Y, Cr, Y] representing two pixels.

Returns:
A pointer to a I420 to 2VUY conversion function, which uses Altivec or MMX when supported.
