Avoid passing function pointers across process boundaries.
This back-patches commit 32470825d36d99a81347ee36c181d609c952c061
into 9.6, primarily to make buildfarm member culicidae happy.
Unlike the HEAD patch, avoid changing the existing API of
CreateParallelContext; instead we just switch to using
CreateParallelContextForExternalFunction, even for core functions.
Petr Jelinek, with a bunch of basically-cosmetic adjustments by me
