Modified files:
        sbin/dhclient  : dhclient.c 

Log message:
Notice when link-timeout expires even if istty(STDERR) hints that dhclient has
already gone daemon. Sometimes it's just that 2>/dev/null or something has
been done.

Should fix problem with sysupgrade when an interface (e.g. a wired interface 
that
has no cable plugged in) never comes up.

Problem reported and debug info from kettenis@, Jean-Philippe Luigi, Thomas L. 
and
Markus Lude. Thanks!
