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).
