Subject: Add Ribose Inc's implementation of the SM3 hashing function with
 tweaks from jsing and myself.  The SM2/SM3/SM4 algorithms are mandatory for
 legal use of cryptography within China and [are] widely applied in the
 country, covering identification/financial cards, contactless, TPM 2.0 and
 PKI.
