input_stream: return allocated input_stream objects
Major API redesign: don't let the caller allocate the input_stream object. Let each input plugin allocate its own (derived/extended) input_stream pointer. The "data" attribute can now be removed, and all input plugins simply cast the input_stream pointer to their own structure (with an "struct input_stream base" as the first attribute).
