45b1fac0ac Fix a bug in btree.c that caused it to report a database as being 
corrupt if it used one of the last 6 slots in a freelist trunk page.
Continue to never use those last 6 slots so that databases from newer
versions are still readable with older versions. (CVS 5344)

this is a true code problem or just an instrumentation problem. (CVS 5240)
