b355d3411e 1) Fix bug with LEFT JOIN ViewX and where clause with ViewX.FieldX IS NULL 
2) When FIRST / SKIP is used in a sub-query it may not be affected by conjunctions in higher contexts.
  Example (should return 1 row instead of 5):
SELECT * FROM
  (SELECT FIRST 5 SKIP 2 cs.* FROM RDB$CHARACTER_SETS cs)
WHERE
  RDB$CHARACTER_SET_NAME starting with 'D'

in its crusade against non-PODs and poodles.

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.
