Better set memory management.
...
At the cost of one pointer per set, sets can now be allocated and freed
more efficiently (especially since malloc might round things up).

Rename setstate_t to set_iter_t.
...
After all, it is an iterator :).

Rewrite set_first() and add set_next().
...
set_first() now returns a pointer to a setstate_t struct that holds the
state necessary for scanning a set. set_next() will automatically delete
the state block when the end of the set is reached. set_delstate() is also
provided to allow early termination of the scan.

Add set_first.
...
It returns the first element of a set. If the set is empty, -1 (unsigned)
is returned.
