'--log-bin-trust-function-creators' affects not only replication of the
stored functions, but also replication of the triggers.


sql/mysqld.cc:
  Updated the description of mysqld '--log-bin-trust-function-creators' option
  to reflect that after introducing TRIGGER privilege this option also controls
  replication of triggers.
sql/sql_trigger.cc:
  Updated the comment to be consistent with the new behaviour,
  introduced by TRIGGER privilege.
