Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

michael@0	9	* SUMMARY: Try assigning arr.length = new Number(n)
michael@0	10	* From correspondence with Igor Bukanov <igor@icesoft.no>
michael@0	11	* See http://bugzilla.mozilla.org/show_bug.cgi?id=101488
michael@0	12	*
michael@0	13	* Without the "new" keyword, assigning arr.length = Number(n) worked.
michael@0	14	* But with it, Rhino was giving an error "Inappropriate array length"
michael@0	15	* and SpiderMonkey was exiting without giving any error or return value -
michael@0	16	*
michael@0	17	* Comments on the Rhino code by igor@icesoft.no:
michael@0	18	*
michael@0	19	* jsSet_length requires that the new length value should be an instance
michael@0	20	* of Number. But according to Ecma 15.4.5.1, item 12-13, an error should
michael@0	21	* be thrown only if ToUint32(length_value) != ToNumber(length_value)
