Go Sockaddr

Socket address convenience functions for Go. go-sockaddr is a convenience library that makes doing the right thing with IP addresses easy. go-sockaddr is loosely modeled after the UNIX sockaddr_t and creates a union of the family of sockaddr_t types (see below for an ascii diagram). Library documentation is available at https://godoc.org/github.com/hashicorp/go-sockaddr. The primary intent of the library was to make it possible to define heuristics for selecting the correct IP addresses when a configuration is evaluated at runtime. See the docs, template package, tests, and CLI utility for details and hints as to how to use this library.
