I took the opportunity to implement this. Now, the bug is fixed.

If you have any chance to test the development version of Emacs (the
upcoming 26.1 release), you could crosscheck this.

Due to the new defstruct and its mechanery, I had to cut Emacs 23
backward compatibility for Tramp 2.3. I don't know how many users are
hit by this; hopefully not too many.

With the default settings for tramp-tests.el, all test cases pass. But
for some other methods, there are still failures. Will continue to test.
