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 | 15 | * UHashTok moved here from uhash.h and renamed UElement. |
| michael@0 | 16 | * This allows users of UVector to avoid the confusing #include of uhash.h. |
| michael@0 | 17 | * uhash.h aliases UElement to UHashTok, |
| michael@0 | 18 | * so that we need not change all of its code and its users. |
