+  *) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
+     All of these option have not worked for some while and are fundamental
+     algorithms.

   *) Make various cleanup routines no-ops and mark them as deprecated. Most
      global cleanup functions are no longer required because they are handled
      via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
