Self-allocated doubly-linked list for Terra


--[[

	Self-allocated doubly-linked list for Terra.
	Written by Cosmin Apreutesei. Public domain.

	Implemented using a dynarray and a freelist, which means that the location
	of the links in memory is not stable between inserts unless the list is
	preallocated and doesn't grow. Indices are stable though and can be used
	to retrieve the same link after any number of mutations.

	local L = list(T,[size_t=int])              create a list type
	var list = list(T,[size_t])                 create a list object

	list:init()                                 initialize (for struct members)
	list:clear()                                remove items, keep the memory
	list:free()                                 free (items are not freed!)
	list:setcapacity(size) -> ok?               set capacity with error checking
	list.capacity                               (write/only) set capacity
	list.min_capacity                           (write/only) grow capacity

	list:link(i) -> &e                          link at index
	e.item -> &t                                link's payload (element)
	e.next -> i                                 (read/only) next link's index
	e.prev -> i                                 (read/only) prev link's index

	list.first -> i                             (read/write) index of first link
	list.last -> i                              (read/write) index of last link

	for i,&e in list do ... end                 iterate links (remove() works inside)
	for i,&e in list:backwards() do ... end     iterate backwards (remove() works inside)

	list:insert_before(i[,v]) -> i              insert v before i
	list:insert_after(i[,v]) -> i               insert v after i
	list:remove(i)                              remove link

	list:move_before(di,i)                      move link at i before link at di
	list:move_after(di,i)                       move link at i after link at di
