[Bug 876829] Re: Oneiric's ifupdown breaks ip aliases

[Patrick Domack]

This corrects ifup, and almost corrects ifdown.

ifdown still downs the whole interface do to the ip link set dev x down
line, it shouldn't be called on alias interfaces, but that is beyond me
at the moment. Also not sure if the tun up/down could use this code
also. The debian/testbuild file needs to be modified to pass for these
modifications

  address 192.168.122.201
  netmask 255.255.255.0
  broadcast 192.168.122.255
  gateway 192.168.122.1

  auto eth0:0
  iface eth0:0 inet static
