Fix the windows binding for getaddrinfo

getaddrinfo should take a double pointer to ADDRINFOA instead of a single pointer. If you call the binding in its current state you will not get back a valid ADDRINFOA struct.

I have also changed the `node` and `service` params to be cstring to avoid having to do `transmute(u8) value`.
