the encoder could attempt to create folding-free short blocks which

This avoids the need for 64-bit addition and is faster on x86_64.
It may be slower on some platforms so the direct solution is still
available in the source.

Adds specialized O(N*log(K)) versions of cwrsi() and O(N) versions of icwrs()
 for N={3,4,5}, which allows them to operate all the way up to the theoretical
 pulse limit without serious performance degredation.
Also substantially reduces the computation time and stack usage of
 get_required_bits().
On x86-64, this gives a 2% speed-up for 256 sample frames, and almost a 16%
 speed-up for 64 sample frames.

fixed point compilation because SCALEIN is a no-op in fixed point
mode but the float interface is still normally +/- 1.0.

This patch adds a seperate define for the scaling factor so people
can adjust it for unusual input levels.

more about how CELT works to determine that.
