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.

0b6956b474 Correct serious bug in AES-CBC decryption when the message length isn't
a multiple of AES_BLOCK_SIZE.
Optimize decryption of all complete blocks in AES-CBC by removing an
unnecessary memcpy().

The error was notified by James Fernandes <jf210032@exchange.DAYTONOH.NCR.com>.
The unnecessary memcpy() was found as an effect of investigating that error.

001ab3abad Use double dashes so makedepend doesn't misunderstand the flags we
give it.
For 0.9.7 and up, that means util/domd needs to remove those double
dashes from the argument list when gcc is used to find the
dependencies.

6f9079fd50 Because Rijndael is more known as AES, use crypto/aes instead of
crypto/rijndael.  Additionally, I applied the AES integration patch
from Stephen Sprunk <stephen@sprunk.org> and fiddled it to work
properly with the normal EVP constructs (and incidently work the same
way as all other symmetric cipher implementations).

This results in an API that looks a lot like the rest of the OpenSSL
cipher suite.
