/**
 * list functions:
 * for each list there is a set of functions, explained using String as example
 *
 * ccsStringListAppend (list, item)
 * Adds an item at the end of the list. Returns the new list.
 *
 * ccsStringListPrepend (list, item)
 * Adds an item at the beginning of the list. Returns the new list.
 *
 * ccsStringListInsert (list, item, position)
 * Adds an item at a given position. Position is 0-based. If position is
 * larger than the amount of items in the list, the item is inserted at the
 * end of the list. Returns the new list.
 *
 * ccsStringListInsertBefore (list, sibling, item)
 * Inserts item before sibling into the list. If sibling is no list member,
 * item is inserted at the end. Returns the new list.
 *
 * ccsStringListLength (list)
 * Returns the amount of items in list.
 *
 * ccsStringListFind (list, item)
 * Finds and returns an item matching <item>. If nothing is found, returns NULL.
 *
 * ccsStringListGetItem (list, index)
 * Returns the list item at position <index>. If index is larger than the
 * amount of items in the list, returns NULL.
 *
 * ccsStringListRemove (list, item, freeObj)
 * Removes item from the list. If freeObj is TRUE, also frees the data item.
 * Returns the new list.
 *
 * ccsStringListFree (list, freeObj)
 * Frees the complete list. If freeObj is TRUE, also frees the data items.
 * Returns the new list (NULL).
