Bug Description

This is to track the fix of upstream http://bugs.mysql.com/bug.php?id=47134 for Percona Server 5.6.

There are two alternative fixes: MariaDB 5.5 fix, and MySQL 5.7.1 fix.

The MariaDB fix has received more testing because of TokuDB being packaged in MariaDB 5.5, on the other hand the MySQL fix has a unit test. Thus let's fix by a combination of the MariaDB fix + MySQL unit test.

Shouldn't affect PXC (since it also implements its own additional XA) due to

#ifndef WITH_WSREP
  DBUG_ASSERT(total_ha_2pc == (ulong) opt_bin_log+1); // only InnoDB and binlog
#endif

in handler.cc

Adding PXC to track the fix that will be merged for this.
