As I mentioned in [1], checking (struct Port)->ssl for NULL to determine
whether TLS is used for connection is a bit of a leaky abstraction, as that's
an OpenSSL specific struct member. This sets the requirement that all TLS
implementations use a pointer named SSL, and that the pointer is set to NULL in
case of a failed connection, which may or may not fit.
Is there a reason to not use (struct Port)->ssl_in_use flag which tracks just
what we're looking for here? This also maps against other parts of the
abstraction in be-secure.c which do just that. The attached implements this.
