Merge the alter table code from MySQL 5.6 into MySQL 5.5 and MariaDB 5.5. This feature supports TokuDB's online schema change features including online index addition and deletion, online column addition and deletion, and online column expansion. All of these operations allow concurrent reads and writes to the relevant tables.
