1cc093c2b5 Partial fix for a problem with LEFT OUTER JOIN. It used to be that the test 
for the right-hand table not matching the left table occurred after all
ON, USING, WHERE clause processing.  The test should occur after ON and
USING clauses are checked but before the WHERE clause is check.  This fix
works as long as the total number of "AND" separated terms in the ON, USING,
and WHERE clause does not exceed 32.  To do: make this work for any number
of terms and add test cases.

f5905aa7be NULL values are distinct. A comparison involving a NULL is always false. 
Operations on a NULL value yield a NULL result.  This change makes SQLite
operate more like the SQL spec, but it may break existing applications that
assumed the old behavior.  All the old tests pass but we still need to add
new tests to better verify the new behavior.  Fix for ticket #44. (CVS 589)

ad3cab52fe Split the IdList structure into IdList and SrcList. SrcList is used to 
represent a FROM clause and IdList is used for everything else.  This change
allows SrcList to grow to support outer joins without burdening the other
uses of IdList. (CVS 584)
