Enhanced Index Structure.
...
1) NULLs on top when sorting on ASC index, DESC stays the same.
2) Support for larger index lengths, can be up to 1/4 page size.
3) Store record-number on non-leafpages for faster lookup in many duplicates.
4) Jump-nodes for faster key-lookup in index on larger page-sizes.
5) Segment selectivity calculation added.

Basic INTL cleanup.
...
- Rework (mostly undo) John's changes
- Some function type safety
- Make INTL OO layer very thin (this should slightly improve performance)
