cursor progression patch

I've worked over my enhanced 5250 protocol patch and now tn5250 supports
cursor progression!  The bad part is that 5250 windows are broken.  That's
because with cursor progression, the 5250 defines a new window
create/destroy method that I haven't completely implemented yet, so 5250
windows are a bit... crashy.  If you use x5250 things don't crash, but the
windows are still messed up.  But if you don't use 5250 windows then
everything works great regardless of your favorite front end (i.e. this
works for tn5250, xt5250, gnome-5250, win32-5250, x5250, etc.).

The patch is too large to include here, so I posted it at:

This is against current cvs HEAD.
