The CBC initialization vector is passed as a const pointer, and then
cast to a non-const pointer to store it in the aes state struct. This
cast can easily be avoided by changing the struct field into a const
pointer.
This imports Tiny AES128 from https://github.com/kokke/tiny-AES128-C for
use in the decoding of OSTC3 firmwares.
This aes-code is released into the public domain.
