This allows a QSharedPointer to be used in contexts where the class in question is still forward-declared. This produced a warning in Qt 4 due to the expansion of the template, even if there was no chance of the pointer being deleted there (because the reference count could not drop to zero). Now, not only is the warning removed, but you can actually have the reference count drop to zero in a forward-declared class and it will do the right thing. That's because the deleter function is always recorded from the point of construction and we're sure that it wasn't forward-declared. The unit test for forward-declarations had to be rewritten. The previous version was passing only because the QSharedPointer object was created under the "tracking pointers" mode, which causes a custom deleter to be used in all cases.
