Aha. This works. If you feel like explaining the C++-technical reason
behind why we need different Reference implementations for the two
cases... Feel free.

I assume I can mix-and-match both, they will use the same (shared)
counters for reference counting?

I see there is no rtl::WeakReference, and no automatic conversion from
rtl::Reference to css::uno::(Weak)Reference; oh well, I can add
".get()" here and there.
