New functions to examine the contents of heap pages, as discussed
recently on -hackers. These are fully integrated into backend.
Designed to be extended for other page layouts/contents. (Heikki has
some similar functions for index pages).
Docs included, applies cleanly, tests good.
I'll maintain this with immediate fixes/additions as we go up to 8.3 and
beyond, to assist review process of various patches that alter page
contents.
