Make the slave die if master is 5.0. Indeed, 5.0 masters send
a Format_description_log_event (or maybe it will be named
Description_log_event) which is not recognized by 4.0, so
a 4.0 can't be a slave of 5.0. We detect it early to produce
a helpful message instead of "corrupted relay log" later.
sql/slave.cc:
Make the slave die if master is 5.0.
