src/backend/commands: vacuum.c

Log message:
Fix VACUUM so that it can use pages as move targets even if they do not
have any newly-dead tuples on them. This is a longstanding deficiency
that prevents VACUUM from compacting a file as much as one would expect.
Change requires fixing repair_frag to not assume that fraged_pages is
a subset of vacuum_pages.
Also make some further cleanups of places that assumed page numbers fit
in int and tuple counts fit in uint32.
