Prefer "::acs::dc call ..." over "::xo::db::sql::..."

Fixes for Oracle 19c: boolean and timestamp handling, *lobs
- fix boolean permission query - function "now()" does not exist, use "CURRENT_TIMESTAMP" instead - revived blob and clob handling in "xo::dc dml" since this is needed for updating - modernize Oracle offset/limit handling - added missing "-dbn" attributes for Oracle xo::dc calls
