Expose CMAC::poly_double as a static function since it looks like I may
want to inline the CMAC computation in EAX mode.
Also optimize CMAC::final_result slightly. Only write to state directly,
instead of also the write buffer (this should help L1 data caching), and
avoid what was basically a no-op where we zeroized part of a buffer and
then xored it against another buffer.
