Bug#19904: UDF: not initialized *is_null per row
The is_null value was initialized once and thereafter only set to indicate
NULL, and never unset to indicate not-NULL.
Now set is_null to false, in addition to only setting it to true when the value
in question is null.
mysql-test/r/udf.result:
Add result.
mysql-test/t/udf.test:
Add test.
sql/sql_udf.h:
Initialize is_null to false before trying to use it, so that historical NULLs
don't affect our operation.
