 The patch in #5357 handles parent/child pages incorrectly in some cases,
 when there are multiple levels of nesting and the posts are included in
 the least optimal order in the import file.  The Level 1 / Level 2 / Level
 3 pages in this export file reproduce the problem:

 testdata/export/asdftestblog1.2007-12-11.xml

 The enclosed patch replaces the two pass processing from #5357 with a
 simpler method.  Posts are imported in a single pass, then the post_parent
 of child pages are updated in backfill_parents() later, once the local
 post ID's of all parents are known.  I also removed a little cruft and
 split the import() function in two for easier testing.

 This passes the updated unit tests here:
