calling convention. (CVS 1324)

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)
