30f7f813ea 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.

80ed147663 The number of channels is now set when creating the states rather than when 
creating the mode. This means that the same mode can be shared for mono and
stereo.

6a97802280 Adjusting the allocation for stereo directly in the alloc function rather than 
in the table.

9dff02188c Minor stuff: preventing float underflow in celt_exp2(), preventing the use of 
intra energy for low bitrates, and a bit of very high bitrate tuning

18c1c22e16 Fix for a mode memory leak -- was still allocating memory for the energy 
allocator which was removed a while ago.

ec836da27c Reduce rounding in the mode allocator and remove a scaling loop. 
This breaks the bitstream.

9a6c496630 Changed the allocator to be smarter about the way it allocates 
fine energy bits. Also, doing better rounding of the bits.

504f8c2597 some tuning to fine energy allocation and prevent it from going above 7 bits 
(at which point, it causes problems)

9eba823cf7 Turns out that the worse case of the vector split is the same as that of the 
pulse split. Also, added an allocation line for even higher bit-rates
