[stunnel-users] patch: round robin load balancing

I noticed that stunnel already does round-robin load balancing of
connections when the DNS name specified by the "connect" option resolves
to multiple IP addresses.

Here is a simple patch which allows the "connect" option to accept a
comma separated list of names instead of just a single name.

This can be used to load balance tunnelled connections across several
servers.  For example, to load balance HTTPS connections across 3 HTTP
servers (localhost:80, anotherhost:8080 and anotherhost:8081), we could

    accept = 443
    connect = 80,anotherhost:8080,anotherhost:8081
