In the case of mmgr/slab.c, a lot of those uses of Size probably
correspond to instantiations of the MemoryContext APIs; so blindly
changing them to "size_t" seems like a bit of a type violation
(and might indeed draw warnings from pickier compilers). Don't
know if any of the other things you've identified here have similar
entanglements.
