      BUG#42079 - Falcon does not reset auto_increment on transactional
                  truncate
      
      With fix for BUG37016 Falcon didn't reset auto_increment counter
      on TRUNCATE, and was falling back to slow row-by-row delete.
      
      With this fix Falcon is accepting quick truncate and is
      resetting auto_increment counter.

  mysql-test/suite/parts/t/disabled.def
  storage/falcon/ha_falcon.cpp

    Re-enabled a test case.
  storage/falcon/ha_falcon.cpp
    With fix for BUG37016 server doesn't disable transaction.
    Fixed condition, that determines if quick truncate is
    acceptable accordingly.
