    fw/b: Add capability to allow tethering to use VPN upstreams

    * Toggled on/off at runtime via a new hotspot lineage setting.

    * Dynamically updates the tethering upstream for existing hotspot
      clients as VPNs are brought up / down or the hotspot setting
      is changed.

    * This implementation depends on fw/b config_tether_upstream_automatic
      being set to true.

    fw/b: Prevent trying to enable hw offload for tethering via VPN upstreams

    * Tethering via VPN upstream requires a sw path.

    * hw offload setup happened to be being disabled anyway owing to a fail
      return code from setDataLimit().  However, it was causing offload to be
      disabled entirely (until next hotspot off / on event).

    * Gracefully skip hw offload for vpn upstreams so that it is automatically
      used again when a vpn is disconnected.
