Fix the discordant data types between flags and the vars used to work with them (really dangerous if the flag is USHORT and you hold it in a UCHAR). Also, get rid of some debris of the uppercased typedefs.

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.
