Bug#19995 (Extreneous table maps generated for statements that do not generate rows):

Switched to writing out table maps for tables that are locked when
the first row in a statement is seen.


mysql-test/include/master-slave.inc:
  Moved code to reset master and slave into separate file.
mysql-test/r/binlog_row_blackhole.result:
  Result change
mysql-test/r/binlog_row_mix_innodb_myisam.result:

mysql-test/r/rpl_row_create_table.result:
  Result change
mysql-test/t/rpl_row_basic_11bugs.test:
  Added test to check that no events are generated when no rows are changed.
mysql-test/t/rpl_row_create_table.test:
  Master log position changed
sql/handler.cc:
  Adding function write_locked_table_maps() that will write table maps for all
  tables locked for write.
  Using "table->in_use" instead of "current_thd" since tables are now locked
  when the function is called.
  Removing old code to write table map.
sql/log_event.cc:
  Added assertion
sql/sql_class.cc:
  Removing code to write "dummy termination event".
sql/sql_class.h:
  Adding getter for binlog_table_maps.
sql/sql_insert.cc:
  Setting thd->lock before calling write_record for the execution of
  CREATE-SELECT and INSERT-SELECT since they keep multiple locks in the
  air at the same time.
mysql-test/include/master-slave-reset.inc:
  New BitKeeper file ``mysql-test/include/master-slave-reset.inc''
