check for SSE bit instead of MMX, as pshufw was introduces in PIII, minor

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.
