This is a counterpart of https://go-review.googlesource.com/37039. This change introduces a package that provides a portable interface for the manipulation of sockets using either syscall.Conn and syscall.RawConn interfaces or the internal/netreflect package appropriately. The package ensures that a package using this works with all supported versions of the Go standard library. Updates golang/go#19051.
