writing DROP and CREATE TRIGGER to binlog, disabling binlogging of substatements, testing. mysql-test/r/rpl_sp.result: result update mysql-test/t/rpl_sp.test: removing useless lines, plus testing replication of triggers sql/sql_trigger.cc: trigger can be used to destroy slave, so only SUPER can create it by default. If create|drop goes ok, binlog CREATE TRIGGER and DROP TRIGGER. sql/sql_trigger.h: disable binlogging of substatements of triggers (even if now triggers can't do updates)
