v2 of checksum patch, using a conditional copy if checksumming is
enabled, so locking is removed.
Thanks to Andres for thwacking me with the cluestick, though I have
used a simple copy rather than a copy & calc.
Tested using make installcheck with parameter on/off, then restart and
vacuumdb to validate all pages.
Reviews, objections, user interface tweaks all welcome.
