Fixed a bug which corrupted the table if the primary key
of a > 8000-byte row was updated.
There are now 3 types of InnoDB Monitors: innodb_monitor,
innodb_lock_monitor, and innodb_tablespace_monitor.
innodb_monitor now prints also buffer pool hit rate and the total
number of rows inserted, updated, deleted, read.
Fixed a bug in RENAME TABLE.
Fixed a bug in replication with an auto-increment column.
