too numerous to be listed here, but include adding a new DES API
(support for the old one is still present).
Changes to the pkgsrc structure include:
* Install the shared libraries with a version number that matches the
OpenSSL version number
* Move some of the less often-used c_* utilities back into the examples
directory.
* Drop support for using the RSAREF library and always use the built-in
RSA code instead.
