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.

 // setVariable can change the types of variables and arguments in functions.

 var g = newGlobal();

 g.eval("function f(a) { var b = a + 1; debugger; return a + b; }");

 for (var i = 0; i < 20; i++)

     assertEq(g.f(i), 2 * i + 1);

 var dbg = new Debugger(g);

 dbg.onDebuggerStatement = function (frame) {

     frame.environment.setVariable("a", "xyz");

     frame.environment.setVariable("b", "zy");

 };

 for (var i = 0; i < 10; i++)

     assertEq(g.f(i), "xyzzy");
