Summary: get-package-attribute sometimes returns "?"

Initial Comment:
In addition to correctly returning unknown when an attribute isn't found get-package-attribute sometimes returns a "?". This causes the scheme code to get peppered with checks for both. eg. spice-sdb. I thought this might be from something in o_attrib_search_object_attribs_by_name but the rabbit hole goes deeper than that, and this being my first foray into gaf and all I chose to fix it in get-package-attribute though maybe someplace else would be better. Of course this means that there are two values that an attribute can't have "unknown" and "?". Not the best situation but it's causing lots of extra bugs in the backends that shouldn't be there. :-)
