Subject: Use more consistent order for Init/Update/Final
Consistently implement the _ex() version after the non-extended versions,
First Cipher Init/Update/Final, then Encrypt, then Decrypt. This only
switches the order of CipherFinal{,_ex} and move the DecryptInit* down,
so they are no longer somewhere in the middle of the Encrypt* functions.
