std: mapping additional libuv ip string helpers.. add test for sockaddr_in6

Browse Source 
.. but the test is kind of broken.. it appears that rust pads structs for
alignment purposes? I can't get the struct to == 28.. that appears to
be the native size of sockaddr_in6.. so we have a size 32 struct, for now.
