Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // Test the functionDisplayName of SavedFrame instances.

 function uno() { return dos(); }

 const dos = () => tres.quattro();

 const tres = {

   quattro: () => saveStack()

 };

 const frame = uno();

 assertEq(frame.functionDisplayName, "tres.quattro");

 assertEq(frame.parent.functionDisplayName, "dos");

 assertEq(frame.parent.parent.functionDisplayName, "uno");

 assertEq(frame.parent.parent.parent.functionDisplayName, null);

 assertEq(frame.parent.parent.parent.parent, null);
