This moves `struct nettle_mac` to nettle-meta.h and provide the meta interface for all defined MAC algorithms. Each meta interface shall provide the following 4 functions: nettle_set_key_func *set_key; nettle_set_key_func *set_nonce; nettle_hash_update_func *update; nettle_hash_digest_func *digest; where set_nonce is only used by UMAC, and expects that the nonce has always the same length as AES_BLOCK_SIZE. For CMAC and HMAC, a no-op set_nonce function is defined. Also the signature of set_key is slightly different from hmac_*_set_key in that it doesn't take key length as an argument. A wrapper function is provided to clamp the length to hash block size.
