      MDEV 4427: query timeouts · cc8aed3e
      Monty authored
      Added MAX_STATEMENT_TIME user variable to automaticly kill queries after a given time limit has expired.
      
      - Added timer functions based on pthread_cond_timedwait
      - Added kill_handlerton() to signal storage engines about kill/timeout
      - Added support for GRANT ... MAX_STATEMENT_TIME=#
      - Copy max_statement_time to current user, if stored in mysql.user
      - Added status variable max_statement_time_exceeded
      - Added KILL_TIMEOUT
      - Removed digest hash from performance schema tests as they change all the time.
      - Updated test results that changed because of the new user variables or new fields in mysql.user
      
      This functionallity is inspired by work done by Davi Arnaut at twitter.
      Test case is copied from Davi's work.
