Subject: Remove PageSetTLI and rename pd_tli to pd_checksum Remove use of
 PageSetTLI() from all page manipulation functions and adjust README to
 indicate change in the way we make changes to pages. Repurpose those bytes
 into the pd_checksum field and explain how that works in comments about page
 header.

Refactoring ahead of actual feature patch which would make use
of the checksum field, arriving later.

Jeff Davis, with comments and doc changes by Simon Riggs
Direction suggested by Robert Haas; many others providing
review comments.
