Done.

Not started. My current idea is to throw out all of the seteuid(),
UserContext(), etc code. Does anybody run a suid-root screen out 
there?
To make everything work again, the suid-root helper needs the
following functionality:

1) attach to multiuser screen
2) remove/set utmp entries (not needed on systems with utempter)
3) chown ptys (not needed on systems with unix98 ptys)

And I forgot one major point:

- change the code so screen *never* blocks on a dead display.

This is not that hard, the biggest part is a reimplementation
of the Msg() mechanism.

Cheers,
