This is a partial port of my patch in MySQL 8.0. In MySQL 8.0, all InnoDB references to DBUG_OFF were replaced with UNIV_DEBUG. We will not do that in MariaDB. InnoDB used two independent compile-time flags that distinguish debug and non-debug builds, which is confusing. Also, make ut_ad() and alias of DBUG_ASSERT().
