- update to 1.4.1:
    * Improve and fix use of getopt_long().
      We musn't use a long option val of 1, since getopt_long() can return
      that value.
      getopt_long() also returns longindex == 0 when there is no matching
      long option, and there needs to be careful checking if there is an
      error to work out whether a long or short option was used, which is
      needed for meaningful error messages.
    * Write assert() messages to syslog.
      assert()s are nasty things, but at least let's get the benefit of
      them, and write the messages to syslog, rather than losing them down
      stderr.
    * Enable sorry server at startup if quorum down due to alpha mode
      If alpha mode is configured on sufficient checkers so that a
      virtual server doesn't have a quorum, we need to add the sorry
      server at startup, otherwise it won't be added until a quorum has
      been achieved and subsequently lost again. In the case where some
      of the checkers remain in the down state at startup, this would have
      meant that the sorry server never got added.
    * For virtual servers, ensure quorum <= number of real servers
      If the quorum were gigher than the number of real servers, the
      quorum for the real server to come up could never be achieved, so
      if the quorum is greater than the number of real servers, reduce it
      to the number of real servers.
    * Fix some SNMP keepalived checker integer types and default values.
      Some virtual server and real server values were being sent to SNMP
      with a signed type whereas the value is unsigned, so set the type
      field correctly.
      Some virtual server and real server values that apply to checkers
      are set to nonsense default values in order to determine if a
