description:
Split aes_cbc_* and aes_xts_* into their own header files.

aes.h will remain just for key setup; any particular construction using
AES can have its own header file so we can have many of them without
rebuilding everything AES-related whenever one of them changes.

(Planning to add AES-CCM and AES-GCM too.)
