Refcount all the IFX_ stream classes all the time.

We can remove a lot of "bOwnsStream" logic in the process.
Always pass these by const reference, in case the called method
wants to hang on to the stream (one exception is where we stick
a raw pointer into a void* slot in a context from another layer).
