This commit essentially has three parts: * Add the AES-CCM encryption hooks. This is in and of itself fairly small, as there is only a small difference between CCM and the other ICM-based algorithms. * Hook the code into the OpenCrypto framework. This is the bulk of the changes, as the algorithm type has to be checked for, and the differences between it and GCM dealt with. * Update the cryptocheck tool to be aware of it. This is invaluable for confirming that the code works. This is a software-only implementation, meaning that the performance is very low. Sponsored by: iXsystems Inc.
