* cbc_crypt()

* Encrypt (or decrypt) len bytes of a buffer buf.
* The length must be a multiple of eight.
* The key should have odd parity in the low bit of each byte.
* ivec is the input vector, and is updated to the new one (cbc only).
* The mode is created by oring together the appropriate parameters.
* DESERR_NOHWDEVICE is returned if DES_HW was specified but
* there was no hardware to do it on (the data will still be
* encrypted though, in software).
