Title: Fixed list/hash autofree strategy

Was breaking systematically since it depended on caller to strdup passed values; omitting this created a hard-to-find error. Now the insert/update methods all duplicate the passed value/item for dynamic containers. If callers also duplicate the item the result is a dangling allocation, which is easy to find.
