Beginnings of EVP cipher overhaul. This should eventually

enhance and tidy up the EVP interface.

This patch adds initial support for variable length ciphers
and changes S/MIME code to use this.

Some other library functions need modifying to support use
of modified cipher parameters.

Also need to change all the cipher functions that should
return error codes, but currenly don't.

And of course it needs extensive testing...

  Changes between 0.9.5a and 0.9.6  [xx XXX 2000]
 
+  *) EVP cipher enhancment. Add hooks for extra EVP features. This will allow
+     various cipher parameters to be set in the EVP interface. Initially
+     support added for variable key length ciphers via the
+     EVP_CIPHER_CTX_set_key_length() function. Other cipher specific
+     parameters will be added later via the new catchall 'ctrl' function.
+     New functionality allows removal of S/MIME code RC2 hack. Still needs
+     support in other library functions, also need to add return codes to
+     some EVP functions.
+     [Steve Henson]

   *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
      this option is set, tolerate broken clients that send the negotiated
      protocol version number instead of the requested protocol version
