[patch] use link-local on dhcp failure.

[Robert Love <rml novell com>]

Yo!

Attached patch implements (working) fallback to link-local IP generation
in the case that DHCP fails on a wired or unencrypted wireless network.

Same behavior as Hadess's patch.

The problem with the previous approach is that DHCP timeout is caught in
the "other" Stage 4, "IP Configure Timeout", which lives in a different
function.

It works.  I am giddy.  May I commit?
