f58c769c37 Cleanup. In geeky words:
PandoraBox* pbox = reinterpret_cast<PandoraBox*>(&can_of_worms);
pbox->open();
pbox->flush();
Nickolay may want to undo my ods.h changes if gcc insists
in its crusade against non-PODs and poodles.

9ddf4b9450 Use compressed index-entries.
This will save 2 bytes on every duplicate entry and pagenumber / recordnumber are stored by 7-bits as needed.

5c3c8abd9a Big cleanup.
God have pity on platform maintainers.
I only can compile/test Win32; sorry, folks.

9ebf93b7b9 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.
