Protobuf message and service definitions.

Makefile generates golang message and service stub implementations into //go/gen/proto/. The generated code is checked into the repository.

Dependencies are git submodules in //proto/third_party.

• You need to build protoc in //proto/third_party/protobuf by running bazel build //:protoc from that directory. Currently tested with bazel version 3.1.0.

• You need to run go build -o ._protoc-gen-go ./cmd/protoc-gen-go in third_party/protobuf-go.

• You need to run go build -o ._protoc-gen-go-grpc ./cmd/protoc-gen-go in third_party/grpc-go/cmd/protoc-gen-go-grpc.

Dependency tracking and hermeticity here are poor.

$ make clean all
