For disconnected/unavailable devices, show the localized
NMDeviceStateReason next to the localized NMDeviceState (and not in
the tooltip). Also, move the code to do this into panel-common rather
to save some duplication.

In bug 689638, the designers only asked for the list icons
to be symbolic, not the big icons in the page headings. The
current code was failing on both ends: virtual devices like
vlan still had non-symbolic icons in the list, and several
pages (e.g mobile and proxy) had symbolic icons in the headings.

It's confusing to call an ethernet device "disconnected" when it is
plugged in but not in use. Just don't say anything instead.
Also, update the icon logic to show the "disconnected" icon in this
state, rather than the "connected" one, since it's confusing for the
icon to change even though the network connection hasn't been
activated.

Bond, bridge, and VLAN devices may not actually exist until their
connections are brought up. So for those types, create device items
(of type NetVirtualDevice or a subclass) as soon as we see the
NMConnection, and then watch for the NMDevice being added later.
