Add the SQLITE_RESULT_SUBTYPE flag for application-defined functions. Add the -DSQLITE_STRICT_SUBTYPE=1 compile-time option that raises an error if any function invokes sqlite3_result_subtype() without the SQLITE_RESULT_SUBTYPE flag. SQLITE_RESULT_SUBTYPE prevents an indexed value of that function from being used to replace an equivalent expression, since the indexed expression does not carry the subtype.
