21cf7079fe Dump our internal AES implementation
This thing was pretty pointless on versions of OpenSSL 0.9.8 and later,
and almost totally pointless on OpenSSL 1.0.0.

Also, favor EVP by default, since it lets us get hardware acceleration
where present.  (See issue 4442)

96ab83d3b6 Improve accuracy of comment about aes_crypt performance
The old comment was from before I tried a huge pile of crazy stuff to
make the inner loop faster.  Short answer: GCC already knows how to
unroll loops pretty well.  Other short answer: we should have made the
relay payload size an even multiple of 4, 8, or ideally 16.

14bc4dcc22 Rename log.h to torlog.h
This should make us conflict less with system files named "log.h".
Yes, we shouldn't have been conflicting with those anyway, but some
people's compilers act very oddly.

The actual change was done with one "git mv", by editing
Makefile.am, and running
   find . -name '*.[ch]' | xargs perl -i -pe 'if (/^#include.*\Wlog.h/) {s/log.h/torlog.h/; }'

a9802d3322 Zero a cipher completely before freeing it
We used to only zero the first ptrsize bytes of the cipher. Since
cipher is large enough, we didn't zero too many bytes. Discovered
and fixed by ekir. Fixes bug 1254.

3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

Re-optimize counter-mode: save about 15% on my core2 by (1) not regenerating the entire counter buffer every time we encrypt a block of keystream (2) using the platform-optimized htonl to convert to big-endian (It's a single instruction on 486 and later ) and (3) not even keeping a separate "counter" and "buffer" when the platform is big-endian. The third still needs testing.

4a0b6af935 Ive spent about 10 hours benchmarking permutations on our counter-mode implementation. This is the one that flies. (Avoid OpenSSL; optimizze rijndael calling convention to avoid needing to marshall and unmarshall counter.) This should speed up cell encryption by about 27%.
