Add bt_multi_page_stats() function to contrib/pageinspect.
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.
