[patch #6210] Make viewport {width, length} under direct ownership of the user interface

[Ben Pfaff]

Follow-up Comment #7, patch #6210 (project pspp):

OK, here's a series of patches that should apply on top of yours.  In order:

viewport-fallback-obviousness.patch
viewport-dont-call-it-a-script.patch
viewport-drop-long-view.patch
viewport-happy-signal-handler.patch

In testing viewport-drop-long-view.patch, I found out that in fact
force_longview() was called when --testing-mode was used (don't know why my
grep missed that earlier).  But I think that the heuristic I used there makes
sense: only a tty has a width, so only wrap messages to the width when going
to a tty.  What do you think?

I didn't look at the GUI half of this yet.

I'm not feeling particularly "with it" today, so there are probably a bunch
of loose ends here, although I did test it.
