SSL: fixed possible segfault with dynamic certificates.

Browse Source 
A virtual server may have no SSL context if it does not have certificates
defined, so we have to use config of the ngx_http_ssl_module from the
SSL context in the certificate callback.  To do so, it is now passed as
the argument of the callback.

The stream module doesn't really need any changes, but was modified as
well to match http code.
