Why not something like:

struct list_node {
struct list_node *prev;
struct list_node *next;
}

struct list {
struct list_node *prev;
struct list_node *next;
}

list_length(struct list *l)
list_add(struct list_node *new, struct list *head)
list_splice(struct list *list, struct list *head)

New:

#define list_sublist_from(node) ((struct list *)node)

So people would be forced to think if he is using a 'list_head'
as a node or as a sublist, and do the right casts to shut up the
compiler (that's why you can't do a typedef list_node list..., for
the compiler to scream...)
