* aes.h (aes_encrypt, aes_decrypt): Declare ctx argument as const.

Also updated implementation.
* blowfish.h (blowfish_encrypt, blowfish_decrypt): Likewise.
* cast128.h (cast128_encrypt, cast128_decrypt): Likewise.
* serpent.h (serpent_encrypt, serpent_decrypt): Likewise.
* twofish.h (twofish_encrypt, twofish_decrypt): Likewise.
