If on an i386, detect existance of the VIA C3 xcrypt-* using sysctl of
the machdep.xcrypt node. If they exist, use the xcrypt-cbc instruction
to accelerate aes-{128,192,256}-cbc, for more than 100x performance
increase. This code has no effect on any cpu... Tested thus far using
openssl speed command, and of course, ssh. 778MB/sec AES-128-CBC
performance at 8192 byte block size.
