[patch] Support for Cell FFT's up to 4K points.

[Don McCoy]

The attached patch provides support for 1-D complex-complex FFTs up to 
4K points in length.  This implementation limits it to 4K to save stack 
space, even though the underlying SPE library routine (libfft) allows up 
to 8K points.

Regards,
