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

const correctness
BOOLEAN -> bool
Vars in scope
Formatting
JRD_REQ -> jrd_req*
JRD_TRA -> jrd_tra*
JRD_REL -> jrd_rel*
JRD_FLD -> jrd_fld*
event -> event_t, EVENT_T dropped, EVENT should go in the future
Frank's corrections
alice's STR -> alice_str*
remote's STR -> rem_str*
etc.
It creates entities and backups and restores for me. :-)

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.
