06c67dbce2 Simplified exp_spreading by unifying both directions. Have to admit I don't 
fully understand why that works!

5215623dcd ensures that the celt header is written as little endian, and also checks 
that the passed size parameter is not < 56.

05686a5d6e As extra safety, make sure not to use pitch prediction when it would make 
the "effective gain" too high (>10 dB).
