This adds the CBC-MAC code to the kernel, but does not hook it up to anything (that comes in the next commit). https://tools.ietf.org/html/rfc3610 describes the algorithm. Note that this is a software-only implementation, which means it is fairly slow. Sponsored by: iXsystems Inc Differential Revision: https://reviews.freebsd.org/D18592
