Here are two more, cumulative with the previous patch and each other:
The first removes the assumption in ordered_set_startup that the
aggcontext can be cached in fn_extra, and puts it in the transvalue
instead.
The second exposes the OSA* structures in a header file, so that
user-defined ordered-set aggs can use ordered_set_transition[_multi]
directly rather than having to cargo-cult it into their own code.
