conf: Allow binding to ports on an interface without a specific address
Somebody might want to bind listening sockets to a specific interface, but not a specific address, and there isn't really a reason to prevent that. For example: -t %eth0/2022 Alternatively, we support options such as -t 0.0.0.0%eth0/2022 and -t ::%eth0/2022, but not together, for the same port. Enable this kind of syntax and add examples to the man page.
