There is a new protobuf library (and corresponding code generator) for Go: google.golang.org/protobuf. It is fairly compatible with the previous v1 API (github.com/golang/protobuf), but there are some changes. This patch adjusts the code and generated files to the new API. The on-wire/on-disk format remains unchanged so this should be transparent to the users.
