- Remove unused LOGSEVERITY_ERROR_REPORT value (see http://crbug.com/352378).
- CefURLRequest in the render process will now always have the UR_FLAG_REPORT_LOAD_TIMING flag set (see http://crbug.com/376025#c15).
- Change CefGeolocationHandler::OnRequestGeolocationPermission return value from void to boolean.
