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 | * Description: |
| michael@0 | 10 | * |

| michael@0 | 12 | * |
| michael@0 | 13 | * Earlier versions of JavaScript supported access to the arguments property |
| michael@0 | 14 | * of the function object. This property held the arguments to the function. |
| michael@0 | 15 | * function f() { |
| michael@0 | 16 | * return f.arguments[0]; // deprecated |
| michael@0 | 17 | * } |
| michael@0 | 18 | * var x = f(3); // x will be 3 |
| michael@0 | 19 | * |
| michael@0 | 20 | * This feature is not a part of the final ECMA standard. Instead, scripts |
| michael@0 | 21 | * should simply use just "arguments": |
| michael@0 | 22 | * |
| michael@0 | 23 | * function f() { |
| michael@0 | 24 | * return arguments[0]; // okay |
| michael@0 | 25 | * } |
| michael@0 | 26 | * |
| michael@0 | 27 | * var x = f(3); // x will be 3 |
| michael@0 | 28 | * |
| michael@0 | 29 | * Again, this feature was motivated by performance concerns. Access to the |
| michael@0 | 30 | * arguments property is not threadsafe, which is of particular concern in |
| michael@0 | 31 | * server environments. Also, the compiler can generate better code for |
| michael@0 | 32 | * functions because it can tell when the arguments are being accessed only by |
| michael@0 | 33 | * name and avoid setting up the arguments object. |
