Drop-in replacement for IO::Socket::INET supporting IPv4 and IPv6

IOSocketIP provides a protocol-independent way to use IPv4 and IPv6 sockets, as a drop-in replacement for IOSocketINET. Most constructor arguments and methods are provided in a backward-compatible way. For a list of known differences, see the IOSocketINET INCOMPATIBILITES section below.

It uses the getaddrinfo3 function to convert hostnames and service names or port numbers into sets of possible addresses to connect to or listen on. This allows it to work for IPv6 where the system supports it, while still falling back to IPv4-only on systems which don’t.
