WXR importing does not treat change of post_parent

Importing of WordPress eXtended RSS (WXR) newly assigns ID to each posts, instead it takes over old ID from exporting. Because the post_parent column of post is not correctly changed to the new ID, this causes break of parent-child relationship between posts. All pages which has parent page and all attachments can be orphaned.
