The mLockdownEnabled boolean and the mLockdownTracker objects are read and mutated in many places involving vpn logic inside of ConnectivityService. This includes codepaths run on the ConnectivityService handler and codepaths run on Binder calls from IConnectivityManager.aidl, however the access to these variables are not synchronized. This patch adds proper synchronization to mLockdownEnabled and mLockdownTracker by moving access to them into the mVpns lock used for all of vpn logic.
