New design for NULL semantics
Now, instead of being specified as part of the SQL type with the type pragma, there are separate null and not_null pragmas. The not_null pragma was used to control NULL-ness of object pointers. Now the two pragmas are used consistently for object pointers and simple values (and in the future will work for composite values and containers).
