e216f1f09d Implement MSSQL-like (standard conforming) behavior regarding default nulls placement. 
Thanks to Arno changes we can map default placement to indices directly for ODS11+.
This should close SF#225218

710037031f 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.

7b99b8a57b Basic INTL cleanup. 
- Rework (mostly undo) John's changes
- Some function type safety
- Make INTL OO layer very thin (this should slightly improve performance)

235db035ce Ok, i'm joining Firebird destruction team with my cleanup: 
1. Bring trace DSQL, DYN and BLR trace logging up-to-date
2. Remove redundant CSB pointer dereferences in BLR parser and request compiler
3. Convert RIGHT JOIN to LEFT JOIN early during BLR parsing
4. Check BLR syntax for unititalized contexts usage
5. Some type-safety and const-correctness fixes

df3c6abf15 1) fix: Unique index must be complete used else we keep on looking for another one. 
2) MERGE can also handle expressions, stupid example :
  SELECT
    *
  FROM
    RDB$RELATIONS r,
    RDB$RELATION_FIELDS rf
  WHERE
    rf.RDB$RELATION_NAME || 'A' = r.RDB$RELATION_NAME || 'A'
3) Do some code style issues
