This avoids an overflow on extreme signals

We now declare that anything that would overflow is not stable enough

Thanks to Mark Harris for pointing it out.

Gives another ~2% speedup

Speeds up the encoder by about 1%

This makes the decoder ~2.5% faster on x86 because the stereo loop
takes the same processing time as one mono loop due to the dependency chain

Reordering the add with VERY_SMALL changes the dependencies cycle from 2 add + 1 mul
(11 cycles on haswell) to 1 add + 1 mul (8 cycles). This makes the entire decoder about
1.5% faster.

We used the SSE reciprocal square root instruction to vectorize the serch rather
than compare one at a time with multiplies. Speeds up the entire encoder by 8-10%.

No measurable speed change.

Speeds up encoding by another ~1-2%

Speeds up CELT encoding by around 5% on x86

(found through fuzzing)

No point in minimizing the rate too since it's almost constant.

Since DLL builds can't include both fixed and float, separate DLL_fixed
configurations added that include fixed silk code and also set FIXED_POINT.

SDLCheck is a superset of BufferSecurityCheck and is off by default.
If it's set, it complains that it's overriden by BufferSecurityCheck.

Warning 4996 is already ignored in other binaries (fopen being deprecated and
suggesting fopen_s).

NoExtensions isn't a valid value for EnableEnhancedInstructionSet in x64 builds.

Run before any other project.

Avoids trying to create and replace version.h more than once which
led to file-locking errors with multicore builds.
