    WL#7266: Dump-thread additional concurrency tests                                                                                                                           
    
    This worklog aims at testing the two following scenarios:
    
    1) Whenever the mysql_binlog_send method (dump thread)
    reaches the end of file when reading events from the binlog, before
    checking if it should wait for more events, there was a test to
    check if the file being read was still active, i.e, it was the last
    known binlog. However, it was possible that something was written to
    the binary log and then a rotation would happen, after EOF was
    detected and before the check for active was performed. In this
    case, the end of the binary log would not be read by the dump
    thread, and this would cause the slave to lose updates.
    This test verifies that the problem has been fixed. It waits during
    this window while forcing a rotation in the binlog.
    
    2) Verify dump thread can send events in active file, correctly after
    encountering an IO error.
