config: Refactor IPCidr and use of InetAddress

Use a canonically-named utility class to tack on methods to the existing
InetAddress class. Rename IPCidr to InetNetwork so it better matches
InetAddress and is more pronouceable :) While here, simplify the
constructor and toString() functions, and properly implement hashCode().
