This is the start of an actor which will be automatically instantiated in the parent and each content process which can be used to route most process-level IPC traffic needed by the extensions framework. It should allow the extensions framework to keep its IPC glue close to the code that uses it, and simplify matters for child-side code which needs to run in both parent and content processes.
