Log Message:
Update "ap-ssl" package to version 2.8.20. Changes since version 2.8.19:
- With OpenSSL 0.9.7, prevent session resumption during a
  renegotiation to force the client to negotiate a new (and
  acceptable to mod_ssl) cipher suite. Additionally, ensure
  that a correct cipher suite has been negotiated afterwards
  (CAN-2004-0885).
- Fixed more printf(3) style format string bugs (not security
  related) which could crash the server if mod_ssl's trace
  or debug log level is enabled.
