CHROME_BROWSER_MEDIA_MEDIA_STREAM_DEVICE_PERMISSIONS_? 


We have so many files named something like media_stream_.... So I don't like a
general name. 
Can you try to come up with a name that motivates the existence of this file and
the methods within?

Yeah, sgtm. I changed it to your suggestion, I think that's fine.
