gio: don't accept nonstandard IPv4 "numbers-and-dots" addresses

Browse Source 
In addition to the standard "192.168.1.1" format, there are numerous
legacy IPv4 address formats (such as "192.168.257",
"0xc0.0xa8.0x01.0x01", "0300.0250.0001.0001", "3232235777", and
"0xc0a80101"). However, none of these forms are ever used any more
except in phishing attempts. GLib wasn't supposed to be accepting
these addresses (neither g_hostname_is_ip_address() nor
g_inet_address_new_from_string() recognizes them), but getaddrinfo()
accepts them, and so the parts of gio that use getaddrinfo()
accidentally did accept those formats.

Fix GNetworkAddress and GResolver to reject these address formats.
