/****h* Component Library/Quick List
* NAME
*	Quick List
*
* DESCRIPTION
*	Quick list implements a doubly linked that stores user provided
*	cl_list_item_t structures.
*	Quick list does not allocate any memory, and can therefore not fail any
*	operations.  Quick list can therefore be useful in minimizing the error
*	paths in code.
*
*	Quick list is not thread safe, and users must provide serialization when
*	adding and removing items from the list. Note that it is possible to
*	walk a quick list while simultaneously adding to it.
*
*	The Quick List functions operate on a cl_qlist_t structure which should be
*	treated as opaque and should be manipulated only through the provided
*	functions.
*
* SEE ALSO
*	Structures:
*		cl_qlist_t, cl_list_item_t, cl_list_obj_t
*
*	Callbacks:
*		cl_pfn_qlist_apply_t, cl_pfn_qlist_find_t
*
*	Item Manipulation:
*		cl_qlist_set_obj, cl_qlist_obj
*
*	Initialization:
*		cl_qlist_init
*
*	Iteration:
*		cl_qlist_next, cl_qlist_prev, cl_qlist_head, cl_qlist_tail,
*		cl_qlist_end
*
*	Manipulation:
*		cl_qlist_insert_head, cl_qlist_insert_tail,
*		cl_qlist_insert_list_head, cl_qlist_insert_list_tail,
*		cl_qlist_insert_array_head, cl_qlist_insert_array_tail,
*		cl_qlist_insert_prev, cl_qlist_insert_next,
*		cl_qlist_remove_head, cl_qlist_remove_tail,
*		cl_qlist_remove_item, cl_qlist_remove_all
*
*	Search:
*		cl_is_item_in_qlist, cl_qlist_find_next, cl_qlist_find_prev,
