requestRouteToHost will only allow system applications to make routes exempt from the VPN's routing rules. If a VPN is currently running and a non-system app requests a route it will only succeed if that host is currently covered by a VPN exempt routing rule. Otherwise it will fail. For example, if a VPN is running and the MMS network is brought online those routes will be added as VPN exempt. If an application then tries to request a route to a MMS endpoint it will succeed because the routes already exist. If an application tries to request a route to a host covered by the VPN the call will fail. Bug: 12937545 Change-Id: If7bcec91bbb96c62c8fb69748c975847e6c00b6f
