This patch exports four tables and the set_key() routine. This ressources can be shared by other AES implementations (aes-x86_64 for instance). The decryption key has been turned around (deckey[0] is the first piece of the key instead of deckey[keylen+20]). The encrypt/decrypt functions are looking now identical (except they are using different tables and key).
