I now tried again with the GUI behavior and think that there's nothing
we should change:

- Clicking with the mouse on the menu bar of the root of a child frame
  should operate on the root frame - this was the behavior ever since
  and I don't think we want to change it.

- If users want to operate on the proper "menu bar" of the child frame,
  they should use the F10 key which pops up the menu bar items in a
  special menu operating on the child frame.  Nothing to change either
  but for the fact that the Help menu appears first.

The behavior on tty frames OTOH should be changed.  When a child frame
is selected and has no menu bar, invoking the menu bar of the root
should show the corresponding menu in the root frame and only have a
key's binding operate on the child frame.  Currently, a user gets the
tmm-menubar in the child frame which is however presumed to operate in
normal sized tty-frames and is completely unsuitable for smaller frames.

I attached a few changes to 'popup-menu' and 'menu-bar-open' which have
the menu bar popups happen in the root frame while the command execution
proper is done again in the child window.  Please have a look.

There are two issues I currently don't understand yet: One is that my
nextstep builds don't make child frames correctly on a GUI any more - I
could bet this worked earlier.  Unfortunately, my earlier ns-builds
currently fail with

libgnustep-gui.so.0.27: cannot open shared object file: No such file or 
directory

so I can't verify that claim any more.  I'm not yet sure whether I
should re-install the old libraries and possibly deleted the newer ones.

The other issue is that on my Xfce terminal F10 activates the terminal's
menu bar which is probably not what the user wants.  But that behavior
might be hardcoded and some different key binding would be needed
instead.  On terminals without built-in menu bars this is obviously not
an issue.
