- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs - Did changes in pbxt and maria storage engines becasue of changes in thd->query - Reverted wrong code in sql_table.cc for how ROW_FORMAT is used. This is a re-commit of Monty's merge to eliminate an extra commit from MySQL-5.1.42 that was accidentally included in the merge. This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In case there are any extra changes done before final MySQL 5.1.41 release, these will need to be merged later before MariaDB 5.1.41 release.
