John Baldwin 0a26f85822 Revert r239356 and use an alternate algorithm.
First, don't exit when the link goes down on an interface.  Instead,
teach dhclient to track changes in link state and to enter the reboot
state when the link on an interface goes up causing dhclient to attempt
to renew its existing lease.

Second, remove the change I added to clear the old lease when dhclient
exits due to an error (such as ifconfig down).  If an interface is
using autoconfiguration it should keep its autoconfiguration as much as
possible.  If the next time it needs a configuration it is able to reuse
the previous autoconfiguration, then leaving the settings intact allows
existing connections to survive temporary outages, etc.
