1) Fix starting with and empty string index problem where empty string is passed in parameter. (STARTING WITH ?) ? = ''
...
2) New index structure ensures that NULLs cannot hold the same key-value as a data value.
3) Ignore NULLs already on scanning index where possible.

Nickolay may want to undo my ods.h changes if gcc insists
in its crusade against non-PODs and poodles.

IMPORTANT - this commit introduces an ODS change!
...
1. Added selectivity to idx_repeat and irtd
2. Let's make the selectivity array independent from ODS
3. Cleanup
TODO - use per-segment selectivities in the optimizer and get rid of idx::idx_selectivity for ever

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)
