Add go.mod and go.sum files to support Go modules.

This commit contains no functional changes; it's just adding config files for
the Go modules facility. Ideally this commit should also be accompanied by a
new version tag, since the current latest tag is v1.0.0 from Nov. 2017, and
several optimizations have been added since then.
