/**********************************************************************
  TODO:

- Do comparison line by line, instead of doing a full comparison of
  the text file.  This will save space as we don't need to keep many
  results in memory.  It will also make it possible to do simple
  'comparison' fixes like accepting the result even if a float differed
  in the last decimals.

- Don't buffer lines from the test that you don't expect to need
  again.

- Change 'read_line' to be faster by using the readline.cc code;
  We can do better than calling feof() for each character!

    It will ignore any errors during these retries. One should use
    connect_n_handle_errors() if he expects a connection error and wants
    handle as if it was an error from a usual statement.

  Connect to a server and handle connection errors in case when they occur.

  SYNOPSIS
    connect_n_handle_errors()
      q                 - context of connect "query" (command)
      con               - connection structure to be used

      create_conn       - out parameter, set to zero if connection was
                          not established and is not touched otherwise

  DESCRIPTION
    This function will try to establish a connection to server and handle
    possible errors in the same manner as if "connect" was usual SQL-statement
    (If error is expected it will ignore it once it occurs and log the
    "statement" to the query log).
    Unlike safe_connect() it won't do several attempts.

  RETURN VALUE
    0 - success, non-0 - failure
