Enhancements the fixed-point approximations of non-linear functions.
...
Accuracy for rsqrt, rcp, cos, and log2 is now at the level of truncation error
for the current output resolution of these functions.
sqrt and exp2 still have non-trivial algebraic error, but this cannot be
reduced much further using the current method without additional computation.
Also updates the fast float approximations for log2 and exp2 with coefficients
that give slightly lower maximum relative error.
Patch modified by Jean-Marc Valin to leave the cos approximation as is and
leave the check for x<-15 in exp2 as is.

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.
