22c268e6c9 Next generation aes-586.pl featuring AES_[en|de]crypt, accessing exclusively 
256 byte S-box. AES_cbc_encrypt needs further work as it should also use
slow routines when processing smaller amount of data.

af8c1d81a3 Reimplement outer rounds as "compact" in x86 assembler. This has rather 
strong impact on decrypt performance, 20-25%. One probably should consider
switching between slower and faster routines depending on how much data
we were asked to process.

dff2922aa7 Add option for "compact" rounds to aes_x86core.c. "Compact" rounds are 
those referencing compact, 256-byte, S-boxes.

985e4c4154 Mitigate the hazard of cache-collision timing attack on last round. The 
only chance for T[ed]4 to get evicted in this module is when its cache
"overlaps" with last 128 bits of key schedule.

9598fa8759 Mitigate the hazard of cache-collision timing attack on last round. Well, 
prefetch could have been moved closer to Td4 references. Something for
later consideration...

bcfd3d68f5 Correct logical error in STRICT_ALIGNMENT check and remove copy of 
eay licence, as module is practically rewritten from scratch [well,
even original submission was obviously "almost, but not quite,
entirely unlike" any other eay *_cfb.c module, not to mention new
functions].

21f0db692d Tune up AES CFB. Performance improvement varies from 10% to 50% from 
platform to platform. Its absolute value is within few percents
marginal from that of ECB.

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...

67ea999d4a This patch was "ignited" by OpenBSD 3>=4 support. They've switched to ELF 
and GNU binutils, but kept BSD make... And I took the opportunity to
unify other targets to this common least denominator...

8359421d90 Default to AES u32 being unsinged int and not long. This improves cache 
locality on 64-bit platforms (and fixes IA64 assembler-empowered build:-).
The choice is guarded by newly introduced AES_LONG macro, which needs
to be defined only on 16-bit platforms which we don't support (not that
I know of). Meaning that one could as well skip long option altogether.
