UdpSocket::bind() accepts invalid IPv6 address

[manuels]

The IPv6 address in

let s = UdpSocket::bind("1200::AB00:1234::2552:7777:1313:34300").unwrap();

is invalid because it includes "::" twice. However, this function call returns Ok()

[shepmaster]

It's also invalid because the last group has 5 digits: 34300
