Bug#17284 erroneous temp table cleanup on slave.

Browse Source 
Idea of the fix is for master to send FD event with `created' as 0
     to reconnecting slave (upon slave_net_timeout, no master crash) to avoid destroying temp tables.
     In a case of a connect by slave to the master after its crash temp tables have been already
     cleaned up so that slave can not keep `orphan' temp tables.
