Why do you have this include twice?

ipc_protobuf_message_macros.h will eventually be included transitively by
common_message_generator.h (this is coming in a subsequent change that depends
on this one). since there are no protobuf-like analogs to constructor_macros.h
and destructor_macros.h, the various IPC_PROTOBUF_MESSAGE_TRAITS_* macros need
to be nulled out here to avoid multiple definition errors.
