You need two instances already because of kiss_fftr (and kiss_fft). The kiss
instances create some data they will need for each call when initializing.

The change would only change the meaning of the length parameter to "length in
the input domain" while before it was "length in the time domain".

The change would have the problem, that it's not easy anymore to see which
lengths are fast lengths as for an inverse fft one would need 2*len - 2 (==
length in the time domain) to be factorizable completely by 2, 3 and 5.

I guess we should keep it as is...
