Original change's description:
> Add ability to emulate degraded network in Call via field trial
> 
> This is especially useful in Chrome, allowing use to emulate network
> conditions in incoming or outgoing media without the need for platform
> specific tools or hacks. It also doesn't interfere with the rest of the
> network traffic.
> 
> Also includes some refactorings.
