Check backward-compatibility

$ go run v2/cmd/cmdv2/main.go | go run v1/cmd/cmdv1/main.go

cmdv2 writes out serialized apiv2.Message to stdout and cmdv1 reads binary from stdin, then encodes it to apiv1.Message.

Check backward-compatibility by using prototool

$ git checkout apiv2
$ prototool break check proto
