c6fa97a6d6 FIPS low level blocking for AES, RC4 and Camellia. This is complicated by 
use of assembly language routines: rename the assembly language function
to the private_* variant unconditionally and perform tests from a small
C wrapper.

Modest improvement coefficients mean that code already had some

c8d5c71af5 Mitigate cache-timing attack in CBC mode. This is done by implementing 
compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
