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.

First attempt at adding a suffix to kiss_fft functions so we can have multiple

copies of the FFT.

Split the radix functions into forward and backward versions, removed the

"inverse" flag from the state so it can be shared between the forward and
inverse transforms.
