SSL: fixed possible use-after-free in $ssl_server_name. The $ssl_server_name variable used SSL_get_servername() result directly, but this is not safe: it references a memory allocation in an SSL session, and this memory might be freed at any time due to renegotiation. Instead, copy the name to memory allocated from the pool.
