 // Browser implementation of DataUseAscriber. Maintains a list of
 // DataUseRecorder instances, one for each source of data, such as a page
 // load.
 //
 // A page includes all resources loaded in response to a main page navigation.
 // The scope of a page load ends either when the tab is closed or a new page
 // load is initiated by clicking on a link, entering a new URL, window location
 // change, etc.
 //
 // For URLRequests initiated outside the context of a page load, such as
 // Service Workers, Chrome Services, etc, a new instance of DataUseRecorder
 // will be created for each URLRequest.
 //
 // Each page load will be associated with an instance of DataUseRecorder.
 // Each URLRequest initiated in the context of a page load will be mapped to
 // the DataUseRecorder instance for page load.
 //
 // This class lives entirely on the IO thread. It maintains a copy of frame and
 // navigation information on the IO thread.
