AES CBC encryption performance

Now encryption for AES CBC mode are computed by the cpu.

Since the CBC mode needs the cipher texts of each previous step to process the next step, and so it isn't possible to begin the encryption of a block until its previous block has been encrypted, we can't hope to do parallel processing during the encryption stage of this mode.

If you want you can re-enable it on the configure command line.
