Still more paranoia in PageAddItem: disallow specification of an item
offset past the last-used-item-plus-one, since that would result in
leaving uninitialized holes in the item pointer array. AFAICT the only
place that was depending on this was btree index build, which was being
cavalier about when to fill in the P_HIKEY pointer; easily fixed.
Also a small performance improvement: shuffle itemid's by means of
memmove, not a one-at-a-time loop.
