Code should not be using these directly, instead they should be resolving these dynamically via the open_map. Rework the common callback code that was using the defines to use symbolic names instead, and localize some of the defines in the ARM code (since it's a bit unclear how many different APIs it supports currently), then remove the defines out of the header so no new code can rely on them.
