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.

 // getLineOffsets on a line that is definitely outside a script returns an empty array.

 var g = newGlobal();

 var dbg = Debugger(g);

 var hits = 0;

 dbg.onDebuggerStatement = function (frame) {

     var offs = frame.script.getLineOffsets(g.line0 + 2);

     assertEq(Array.isArray(offs), true);

     assertEq(offs.length, 0);

     hits++;

 };

 g.eval("var line0 = Error().lineNumber; debugger;");

 assertEq(hits, 1);
