The probability stuff is mainly because I've been too lazy so far (patch
welcome!). OTOH, The reason why the FFT isn't included is because the
FFT is the part of the code that's the most likely to be changed. It's
very common to have a highly-optimised FFT that one can use instead of
the generic one provided in CELT.
