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 | 8 | Implementations for a bunch of useful RDF utility routines. Many of |
| michael@0 | 9 | these will eventually be exported outside of RDF.DLL via the |
| michael@0 | 10 | nsIRDFService interface. |
| michael@0 | 11 | |
| michael@0 | 12 | TO DO |
| michael@0 | 13 | |
| michael@0 | 14 | 1) Make this so that it doesn't permanently leak the RDF service |
| michael@0 | 15 | object. |
| michael@0 | 16 | |
| michael@0 | 17 | 2) Make container functions thread-safe. They currently don't ensure |
| michael@0 | 18 | that the RDF:nextVal property is maintained safely. |
