To me, that looks better than the union.

Although AFAICT, stream_directory_t is a "subset" of stream_t, and 
stream_extractor_t would also be a subset except for the identifier. Then you 
don´t even need new types: you can just define a new pf_activate callback 
prototype to carry the identifier.

That being written, I have not actually checked if that would enable any 
further simplification on the core side. I just hope it would allow treating 
extractors and directories as regular streams for purpose other than 
instantation.
