* Simple doubly-linked list implementation. This implementation assumes that
* each element contains an embedded mdb_list_t structure. An additional
* mdb_list_t is used to store the head and tail pointers. The caller can
* use mdb_list_prev() on the master list_t to obtain the tail element, or
* mdb_list_next() to obtain the head element. The head and tail list elements
* have their previous and next pointers set to NULL, respectively.
