ndb - still compiler warnings

3470 Martin Skold 2011-09-09
Added new abort phase for online alter to support the rollback of add index during failure in mysql-5.5 (for example at DDL lock timeout) in mysql-5.5.
Enabled innodb_mysql_sync and kill tests and added new test case in ndb_alter_table_online2.
