3b167c7583 Additional test cases added. The following bug fixed: A segfault was occurring 
if a VIEW consisted of a join with a USING clause. (CVS 651)

c9b84a1fb1 This patch contains the beginnings of the data-typing infrastructure. 
The new build-in TypeOf() function is added.  New opcodes for doing
pure text comparisons are added.  Most changes are disabled pending
the 2.6.0 release. (CVS 632)

f570f011eb Refinements to NULL processing: NULLs are indistinct for DISTINCT and UNION. 
Multiplying a NULL by zero yields zero. In a CASE expression, a NULL comparison
is considered false, not NULL.  With these changes, NULLs in SQLite now work
the same as in PostgreSQL and in Oracle. (CVS 600)

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)
