I understand there is history to this API, and we need to be
compatible, but the end result is awkward.

I'm wondering whether it would be better to just have a new set of
functions like accumArrayResultElem, etc., and only allow astate=NULL
in the original accumArrayResult(). That cure might be worse than the
disease though.
