When inet_parse() parses the hostname, it is forcing the has_ipv6 && ipv6 flags if the address contains a ":". This means that if the user had set the ipv4=on flag, to try to restrict the listener to just ipv4, an error would not have been raised. eg -incoming tcp:[::]:9000,ipv4 should have raised an error because listening for IPv4 on "::" is a non-sensical combination. With this removed, we now call getaddrinfo() on "::" passing PF_INET and so getaddrinfo reports an error about the hostname being incompatible with the requested protocol: qemu-system-x86_64: -incoming tcp:[::]:9000,ipv4: address resolution failed for :::9000: Address family for hostname not supported Likewise it is explicitly setting the has_ipv4 & ipv4 flags when the address contains only digits + '.'. This has no ill-effect, but also has no benefit, so is removed.
