Use a local ".cache" directory in the repository root for the cache
instead of a directory in /tmp. On many operating systems, files are arbitrarily
purged as part of the OS' cleanup procedures, leading to obscure failures.
Since the build cache is in the repo root, we adjust the invocation of gofmt
to only act upon the set of Go files tracked by git.

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.
