/* List object interface */
Another generally useful object type is an list of object pointers.
This is a mutable type: the list items can be changed, and items can be
added or removed. Out-of-range indices or non-list objects are ignored.
*** WARNING *** PyList_SetItem does not increment the new item's reference
count, but does decrement the reference count of the item it replaces,
if not nil. It does *decrement* the reference count if it is *not*
inserted in the list. Similarly, PyList_GetItem does not increment the
returned item's reference count.
/* Vector of pointers to list elements. list[0] is ob_item[0], etc. */
/* ob_item contains space for 'allocated' elements. The number
* currently in use is ob_size.
* 0 <= ob_size <= allocated
* ob_item == NULL implies ob_size == allocated == 0
* list.sort() temporarily sets allocated to -1 to detect mutations.
* Items must normally not be NULL, except during construction when
* the list is not yet visible outside the function that builds it.
