Hal 0.4x does netlink monitoring, that got moved to NM when david
decided that HAL shouldn't be doing link status stuff.

I'm trying to distill a testcase that shows this.  I've got one that
works with the GObject stuff, I'm bringing that down to a plain file
descriptor-based testcase now.  So we'll see.  But its an awefully long
time between when mii-tool shows the link is gone (which is polling of
course) and when the GObject based testcase actually gets notified that
the link is gone (which is listening to the netlink socket).

nm-netlink-monitor.c came along with the move to more recent HAL, I
think for HAL 0.5x and dbus 0.3x.  Previously, the netlink code lived in
HAL's linux backend.
