fixed-point: changed find_spectral_pitch() to use single-precision (16-bit) FFT.
...
This involved adding kfft_single.[ch] that redefines kiss_fft a second time
with a different prefix. All this is still a bit of a mess now. The mask
had to be converted to 16-bit input, but we're still using floats to apply it.

Everything converted to use kiss-fft. Got rid of smallft and fftwrap.
...
Code much leaner now.
