Fix updating buffer menu after invoking "M-x term"

Browse source 
The doc string of 'frame-or-buffer-changed-p' says not to call it
with the nil argument, but term.el did.  Since "M-x term" puts
'term--update-term-menu' on the 'menu-bar-update-hook' ahead of
'menu-bar-update-buffers', it caused the latter decide that there
was no change in buffers, because the internal state variable
used by 'frame-or-buffer-changed-p' when called with the nil
argument was reset by 'term--update-term-menu'.  Fix that by using
a non-nil state variable.
* lisp/term.el (term--buffers-changed): New variable.
(term--update-term-menu): Use it when calling
'frame-or-buffer-changed-p'.  (Bug#80231)
