Pat, thanks for converting the EDD code to sysfs.  Is struct attribute going
to grow some form of existance test, something like I had done before?

This allows attributes to be on def_attrs[] but depending on presence of
existance test (no test means true) and test result, not all attributes for
all similar objects get files created.  This cleanly handles cases where not
all attributes are implemented or valid for all objects of a given type, and
keeps the object's directory free of extraneous invalid files.

Thanks,
Matt
