Add network address and socket types
Types and methods for dealing with IPv4 and IPv6 addresses (and UNIX domain socket addresses under UNIX). This does not include code for actual socket I/O. Originally from "gnio". Much of the code was written by Christian Kellner, Samuel Cormier-Iijima, and Ryan Lortie. Part of #548466.
