Add support for AES-CCM to the crypto library. This will be used to provide a streamlined implementation of the "ccm(aes)" crypto_aead algorithm. Most users of "ccm(aes)" will also be able to switch to the library, which as usual will be faster and simpler, e.g.: - fs/smb/client/ - fs/smb/server/ - net/mac80211/ - net/mac802154/ (I've already written proof-of-concept patches for all the above, and they helped inform the API design.) As in the AES-GCM API, incremental operation is supported. It has to be used carefully, especially when decrypting, but it makes the API general enough to work well for all users. The AES-CCM library code calls aes_cbcmac_blocks() directly, bypassing the higher-level aes_cbcmac_init(), aes_cbcmac_update(), and aes_cbcmac_final(). The latter set of functions is useful only for AES-CCM, so they don't make sense to keep around and will be removed once the "ccm(aes)" crypto_aead starts using the AES-CCM library. Initial test coverage is provided by the crypto_aead support added in a later commit. I'm planning a KUnit test suite as well.
