Changed all the celt*int*_t types to remove the _t suffix, which is reserved
...
by POSIX. The other _t types that are not part of the API are still there
for now. Also, got rid of all that was left of the 64-bit types.

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.
