Since the webrtc_common build target does not have visibility set, we cannot easily use BitrateAllocation in other parts of Chromium. This is currently blocking parts of chromium:794608, and I know of other usage outside webrtc already, so moving it to api/ should be warranted. Also, since there's some naming confusion and this class is video specific rename it VideoBitrateAllocation. This also fits with the standard interface for producing these: VideoBitrateAllocator.
