+1 --- seems like a bunch more mechanism than is warranted. Let's
just open-code it in pnstrdup. We can rely on strnlen, since that's
already supported, and there's not much more there beyond that.

There's a fair number of uses of pnstrdup in the backend. While it
wouldn't be too painful to rename them, I'm not sure I see the point.
(What I'd really argue for, if we did rename, is "pstrndup".)
