This refactors transform_todos() to work on a todo_list. The function is renamed todo_list_transform(). As rebase -p still need to check the todo list from the disk, a new function is introduced, transform_todo_file(). It is still used by complete_action() and edit_todo_list() for now, but they will be replaced in a future commit. todo_list_transform() is not a static function, because it will be used by edit_todo_list() from rebase-interactive.c in a future commit.
