7b22ee8ecb Add support of CAST(expression AS datatype(length)) 
CAST(expression AS datatype(length)) construction is a part of
ANSI SQL-92 standard. So we have to support it.

cdd271490b Allow more variations of LIMIT/OFFSET 
In addtion to already supported LIMIT/OFFSET variants allow more to be parsed

Legacy:
  - LIMIT int
  - LIMIT int OFFSET int

Enhancement:
  - OFFSET int             (no limit)
  - LIMIT ALL              (no limit)
  - LIMIT NULL             (no limit)
  - LIMIT ALL OFFSET int   (no limit, but offset)
  - LIMIT NULL OFFSET int  (no limit, but offset)

Also ensures negative limits / offsets are set to kNoLimit/kNoOffset

66688f7199 Adjust Table Join Types 
Consolidate LeftOuter/Left and RightOuter/Right as they are
by definition the same.
Similar consolidate FullOuter/Outer/Full ... with Outer (as in the
parser) not part of standard, but "full" missing. Allowing all three.

This commit potentially breaks other programs as kJoinLeftOuter and kJoinRightOuter
are eliminated

66804a6281 Allow '==' to be parsed as equal operator in expressions. 
SQLite allows for this and it is in the same spirit as allowing both != and <>
for non equality.

daf8fe7a45 Changing Grammar to extend CASE WHEN statement: 
- allow multiple WHEN statements
- allow for syntax like `CASE x WHEN 1 THEN 2 WHEN 3 THEN 4 ELSE 5 END`
NOTE: This changes also the way the CASE operator is stored:
- CASE [expr] exprList [ELSE expr2] END
- exprList holds each of the WHEN statements with:
  expr := WHEN, expr2 := THEN

Added also tests in test/select_tests.cpp
and adapted the existing one to reflect the new storage
