Given this is JSON any plan to just check-in "global_metadata.json"
somewhere in tools/ with a script that queries for a set of fields and
spits them out into a Linux data structure + set of TD_SYSINFO_*_MAP()
calls? Then no future review bandwidth needs to be spent on manually
checking offsets names and values, they will just be pulled from the
script.
