SMS4 Sub-Library of GMSSL

Encryption modes:

ECB: encrypt or decrypt a block, process only one block per call.
CBC: process variable length input with zero padding, IV works as both input and output.
CFB: same as CBC
OFB: same as CBC

Optimization for specific architecture:

AVX2: support ECB, CTR and CBC-decrypt (todo)
KNC-NI: support ECB, CTR and CBC-decrypt (todo)

Some future plans:

more operation modes, GCM, XTS, FFX, OFB ...
more optimiazations: ARM/NEON, X86 ASM, GPU, ...
secure implementation: Bit Slicing, Timing attack ...
formally verified.
