This makes conversion to using list.h easier because the compiler will error
on an unknown field name rather than accepting `head` and `tail` and missing
some changes.

These list can be embedded into structures and structures can be members of
multiple lists. Moreover, this is done without dynamic memory allocation.
That is, this is legal:
typedef struct item_st ITEM;
struct item_st {
...
OSSL_LIST_MEMBER(new_items, ITEM);
OSSL_LIST_MEMBER(failed_items, ITEM);
...
};
DEFINE_LIST_OF(new_items, TESTL);
DEFINE_LIST_OF(failed_items, TESTL);
struct {
...
OSSL_LIST(new_items) new;
OSSL_LIST(failed_items) failed;
...
} *st;
ITEM *p;
for (p = ossl_list_new_items_head(&st->new); p != NULL;
p = ossl_list_new_items_next(p))
/* do something */
