Remove "(c)". Same in other new files.

Use full path. "CONTENT_PUBLIC_..._WEBRTC_CALLBACK_INTERFACE_H"

[Ivo-OOO until feb 6, 2016/05/18 16:26:55]

Done.

Which of the functions are called from //chrome? If it's just setting callbacks,
it should be possible to add those functions to another existing class in
content public. Add a //content reviewer asap to review if this is OK and to get
guidance on how the public folder should be used.

The class needs a comment describing it, if kept.

I removed it, and moved the functions to RenderProcessHost. Would indeed be good
to get input from a //content reviewer.

Callbacks should be passed by const reference. Same for line 35.

Done.
