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.

libdes (which is still used out there) or other des implementations,
the OpenSSL DES functions are renamed to begin with DES_ instead of
des_.  Compatibility routines are provided and declared by including
openssl/des_old.h.  Those declarations are the same as were in des.h
when the OpenSSL project started, which is exactly how libdes looked
at that time, and hopefully still looks today.

The compatibility functions will be removed in some future release, at
the latest in version 1.0.

VMS as well :-).

types.h to ossl_typ.h.
Also, it seems like krb5 was forgotten in some places.

At the same time, add VMS support for Rijndael.

centralise those hacks in crypto/symhacks.h and use it everywhere it's
needed.
