If the final chunk of an oversized tuple being written out to disk was exactly 32760 bytes, it would be corrupted due to a fencepost bug. Bug #17619. Back-patch to 11 where the code arrived. While testing that (see test module in archives), I (tmunro) noticed that the per-participant page counter was not initialized to zero as it should have been; that wasn't a live bug when it was written since DSM memory was originally always zeroed, but since 14 min_dynamic_shared_memory might be configured and it supplies non-zeroed memory, so that is also fixed here.
