[stunnel-users] SSL renegotiation patch

since I couldn't find a better place I'm sending a simple patch that
allows to disable SSL renegotiation here. Possible reasons for this:
- famous renegotiation SSL flaw, patched in OpenSSL a long time ago,
but not everyone can or want to upgrade OpenSSL
- renegotiation makes some DoS attacks much easier (see
http://www.thc.org/thc-ssl-dos/), regardless of it being a secure one
or not
- it is really not needed in many cases

The approach is based on what is being done in Apache. The default is
to allow renegotation, so there should be no surprises for anyone
after upgrade. Patch applies on latest (4.54b4) stunnel beta. Feel
free to comment:)
