Bug#36099 replicate-do-db affects replaying RBR events with mysqlbinlog

      
The replication filtering rules were inappropiately applied when
executing BINLOG pseudo-query.  The rules are supposed to be active
only at times when the slave's sql thread executes an event.
            
Fixed with correcting a condition to call replication rules only if
the slave sql thread executes the event.

mysql-test/suite/rpl/r/rpl_binlog_query_filter_rules.result:
  new result file
mysql-test/suite/rpl/t/rpl_binlog_query_filter_rules-master.opt:
  a filtering option that would refuse to replicate a row event of the main test on
  slave
mysql-test/suite/rpl/t/rpl_binlog_query_filter_rules.test:
  a regression test for the bug
sql/log_event.cc:
  avoiding to call the filtering rules if the execution thread is not a slave.
