code review 7392049: Add 'go-mode-show-gofmt-errors' to control displa...

Add 'go-mode-show-gofmt-errors' to control display of gofmt errors.

      Set the variable to nil to completely ignore gofmt errors, or non-nil
      to display the errors in a buffer. The value default to 't.

      Documentation about the variable can be displayed within Emacs using
      'M-x describe-variable'.

      Some people like the ability to temporarily disable gofmt errors
      when saving a file while using gofmt to autmoatically format code
      using the before-save-hook. To do this, use the following:

      (defun my-gofmt-before-save-hook ()
	  (let ((go-mode-show-gofmt-errors nil))
      (when (eq major-mode 'go-mode) (gofmt))))
  (add-hook 'before-save-hook #'my-gofmt-before-save-hook)
