Begin moving VPN to NetworkStateTracker pattern.
Created base tracker that handles common bookkeeping, and move VPN
to become a tracker. VPN status is now reflected in NetworkInfo, and
is mapped to LegacyVpnInfo.
Legacy VPN now "babysits" any init services it starts, watching for
when they stop unexpectedly.
