Brooks Davis 4e7ff69a4c Introduce a new function, ifexists and use it to avoid attempting to
touch interfaces that don't actually exist in the stop case.  In the
process move some IPv4 specific code from ifconfig_down to ipv4_down.

This should solve problems with ifconfig: error messages on boot when
interfaces are renamed.
