Add go_package

[tomwilkie]

The expected contents of go_package has changed, see golang/protobuf#139

This is needed to build stuff with bazel - see bazel-contrib/rules_go#836

You also need to modify the gogoproto/Makefile

protoc --gogo_out=Mgoogle/protobuf/descriptor.proto=github.com/gogo/protobuf/protoc-gen-gogo/descriptor:../../../../ --proto_path=../../../../:../protobuf/:. *.proto

And regenerate the code.

And then it should be ready for merge.

Thanks @awalterschulze, done that now.

[awalterschulze]

You forgot to update the Makefile I think.

[tomwilkie]

@awalterschulze should be all fixed, sorry about that.

[awalterschulze]

Cool :)
Thank you for the work.

[tomwilkie]

No worries - thank you!
