IPC glue between cast library transport and encoders.

This CL lets the cast library run the packetizing and encryption in the browser and the video and audio encoding in the renderer. The encoded data is sent over IPC to the browser.

[GCM] Hooking up unregistration

* Implemetning GCMClientImpl.Unregister, added UnregisterCompleted
* Added OnUnregisterFinished to GCMClient::Delegate - the status is passed as a bool, because we ignore it anyway, and it is simply a hook for testing. Functionality is triggered in response to downstream message and not user's interaction.
* Added a test that consumes the delegate hook.
* I considered removing messages related to APP ID, but decided not to add that functionality to GCM Store, as those messages would be sent to MCS before we realize that the app is uninstalled, and there is no point in writing code that would never really do much.
