table_id is defined differently in sql/table.h vs sql/log_event.h

Description:
Binary log structure assumes that table_id in the event can be ulong, while the value is then assigned to table_id filed in TABLE structure that is defined as uint. This can cause overflow and problems during replication (events are not applied to correct table).

See https://bugs.launchpad.net/percona-server/+bug/1070255 for more details on when overflow can happen and real impact for replication.

How to repeat:
Just do code review.

[openxs@chief mysql-5.6]$ grep -n 'table_id;' sql/table.h
1569: uint table_id; /* table id (from binlog) for opened table */
[openxs@chief mysql-5.6]$ grep -n 'table_id;' sql/log_event.h
3794: ulong get_table_id() const { return m_table_id; }
3859: ulong m_table_id;
3983: ulong get_table_id() const { return m_table_id; }
4078: ulong m_table_id; /* Table ID */

See http://bugs.mysql.com/bug.php?id=67352 for details.

We need back port the fix to PS 5.5
