What we call an arena_ind is really the index associated with some particular set of ehooks; the arena is just the user-visible portion of that. Making this explicit, and reframing checks in terms of that, makes the code simpler and cleaner, and helps us avoid passing the arena itself all throughout extent code. This lets us put back an arena-specific assert.
