CMAC and GMAC: code and document mismatch

[chih-kao]

I'm testing ACVP Message Authentication Algorithms (https://pages.nist.gov/ACVP/draft-fussell-acvp-mac.html) and find some JSON fields discrepancy between the documents and the actual vectors.

	Documents	Actual vectors
CMAC-AES Test Case	msg	message
CMAC-TDES Test Group	keyLen	keyingOption
CMAC-TDES Test Case	msg	message
		key (not in document)
AES-GMAC Test Group		payloadLen (not in document)
	ivGenMode (not in actual vectors)
