Pushed this; grepping found a couple other places that could be replaced
by the macros, so I did.
I didn't include the JsonContainerIsEmpty macro, though. It wasn't used
anywhere, and I'm not exactly convinced that "IsEmpty" is more readable
than "Size == 0", anyhow. We can add it later if the use-case gets
stronger.

I'll look at the rest of this in a bit.
