This is like the existing bt_page_stats() function, but it can report on a range of pages rather than just one at a time. I don't have a huge amount of faith in the portability of the new test cases, but they do pass in a 32-bit FreeBSD VM here. Further adjustment may be needed depending on buildfarm results.
