v17

0001
- array_in now repackages cast errors as warnings and skips the stat, test
added
- version parameter added, though it's mostly for future compatibility,
tests modified
- both functions delay object/attribute locking until absolutely necessary
- general cleanup

0002
- added version parameter to dumps
- --schema-only will not dump stats unless in binary upgrade mode
- stats are dumped SECTION_NONE
- general cleanup

I think that covers the outstanding issues.
