Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

 // Changing arguments.length affects a for-of loop iterating over arguments.

 load(libdir + "iteration.js");

 Object.prototype[std_iterator] = Array.prototype[std_iterator];

 var s;

 function f() {

     arguments.length = 2;

     for (var v of arguments)

         s += v;

 }

 s = '';

 f('a', 'b', 'c', 'd', 'e');

 assertEq(s, 'ab');
