BUG#15872504 - REMOVE MYSQL-TEST/INCLUDE/GET_BINLOG_DUMP_THREAD_ID.INC
=== Problem ===
The file named "mysql-test/include/get_binlog_dump_thread_id.inc" is not
used anywhere. In any case, this file does wrong things in the wrong way:
1) The file seems to assume there is only one dump thread, but there may
be many.
2) you can get this information in a much easier way using the command:
"select thread_id from threads where processlist_command="Binlog Dump";"
=== Fix ===
removed file 'mysql-test/include/get_binlog_dump_thread_id.inc'
