mysqltest can now talk to manager and start/stop servers with

server_start/server_stop
changed rpl000018 to use the new server restart feature instead of a
hack


BitKeeper/deleted/.del-rpl000018-master.sh~bc8072e13b26b005:
  Delete: mysql-test/t/rpl000018-master.sh
client/mysqltest.c:
  server_start/server_stop
mysql-test/mysql-test-run.sh:
  tell mysqltest about the manager
mysql-test/r/rpl000018.result:
  fixed bug
mysql-test/t/rpl000018.test:
  use server restart instead of fake binlog hack
sql/log_event.cc:
  so far useless change

client/mysqltest.c
