BUG#38178: rpl_loaddata_map fails sporadically in pushbuild

Problem: master binlog has 'create table t1'. Master binlog
was removed before slave could replicate it. In test's cleanup
code, master did 'drop table t1', which caused slave sql
thread to stop with an error since slave sql thread did not
know about t1.
Fix: t1 is just an auxiliary construction, only needed on
master. Hence, we turn off binlogging before t1 is created,
drop t1 as soon as we don't need it anymore, and then turn
on binlogging again.


mysql-test/include/show_binlog_events.inc:
  Filter out directories and block_len from
  LOAD DATA INFILE events.
mysql-test/suite/rpl/r/rpl_loaddata_map.result:
  updated result file
mysql-test/suite/rpl/t/rpl_loaddata_map.test:
  Turn off binlogging while t1 is used, drop t1 as soon
  as we don't need it anymore, and turn on binlogging again.
  Also added some comments and replaced 'show binlog events'
  by 'source include/show_binlog_events.inc'.
