* Simple default implementation of a hash set. The stored items are
* zero-terminated strings. The hash table does not manage the
* allocation of the strings, like it doesn't manage any stored items.
* However, it items are created with, say, strndup, a destructor can be
* provided to free each item when clearing the table. The remove
* operation also returns the removed item so it can be deallocated by
* callee.
*
* In general, the key and the item are different, but here they are the
* same. Normally the key would be referenced by the item.
