gtk-doc recognizes that #NMFoos is the plural of #NMFoo now, so you
don't need to put an empty comment between the type name and the "s"
to make it work. (Unfortunately, it's not smart enough to realize that
"NMIP4Addresses" is the plural of "NMIP4Address".)
Also, add some missing "#"s noticed along the way.
When using a private connection, we need to use dbus_g_proxy_new_for_peer()
because the bus isn't involved. Since many parts of libnm-glib create a
proxy for their corresponding remote object, consolidate the proxy creation
logic.
A later patch will add logic to use a private connection versus a bus-based
one.
Do NMSettingConnection:interface-name matching on the client side as
well, so that, eg, nm-applet does not list connections under the wrong
device.
(Also, move some return-if-fail checks from the subclass method
implementations into the wrapper function.)
