Darin, John - I only need either one of you to take a look, whoever has time.

Also: I was not sure about naming of the data members of this new struct
WorkerHostMsg_PostConsoleMessageToWorkerObject_Params. I wanted them to
literally repeat WebWorkerClient::postConsoleMessageToWorkerObject() parameters
since the message is based on this protocol, but WebWorkerClient uses WebKit
camelCase names rather then under_score names. What do you think would be better
here?

Thanks for doing this, comments below

We always use under_score names in code in the chrome repository (except for
WebKit api stuff, but that's because it'll move to WebKit repository when it's
complete), so these names should be switched.

Also the code in ipc_message_macros.h isn't needed anymore
