Title:
  bash completion not working: uses deprecated have()

Bug description:
  bash completion, defined in /usr/share/bash-
  completion/completions/ufw, doesn't work: the completion is not
  dynamically loaded, because it uses deprecated helper function have().

  According to /usr/share/bash-completions/bash_completion, which
  defines the helper functions:

  # Backwards compatibility for compat completions that use have().
  # @deprecated should no longer be used; generally not needed with dynamically
  #             loaded completions, and _have is suitable for runtime use.

  and at the end of the file:

  unset -f have
  unset have

  which means: function have() is not available for usage. The bash
  completion for ufw conditionally defines _ufw and the comspec:

  have ufw &&                                                                   
                                                                                
                                    
  _ufw()
  ...

  [ "$have" ] && complete -F _ufw ufw

  These should be changed to:

  _have ufw &&                                                                  
                                                                                
                                     
  _ufw()
  ...

  _have ufw && complete -F _ufw ufw
