Package protogen provides support for writing protoc plugins.
A "plugin" in this case is a program run by protoc to generate output.
The protoc-gen-go command is a protoc plugin to generate Go code.
cmd/protoc-gen-go/golden_test.go is mostly a straight copy from
the golden test in github.com/golang/protobuf.

Use module support in Go1.11 to download the exact version of dependencies
as specified in the go.mod file, this is contrary to "go get -u", which grabs
the latest version, making reproducible builds and tests difficult.
In order for Go1.9 and Go1.10 to work, we also emit a vendor directory for
pre-module support.
Lastly, check whether the go.mod or go.sum files changed
(by shelling to "git diff"). This provides protection in case
a new dependency was added and the go.mod file was not updated.
