Blazingly fast X64 ASM implementation of Salsa20/12
This is ripped from the cnacl source. The actual code is by Danial J. Bernstein and is in the public domain.
This is included on Linux and Mac 64-bit builds and is significantly faster than the SSE intrinsics or C versions. It's used for packet encode/decode only since its use differs a bit from the regular Salsa20 C++ class. Specifically it lacks the ability to be called on multiple blocks, preferring instead to take a key and a single stream to encrypt and that's it.
