Rename _nm_object_handle_properties_changed(), etc, to be about
properties in general, rather than just property changes.

Interpret func==NULL in NMPropertiesInfo as meaning "use
_nm_object_demarshal_generic", and then reorder the fields so that you
can just leave that field out in the declarations when it's NULL.

Add a way to register properties that exist in D-Bus but aren't
tracked by the NMObjects, and use that for NMDevice's D-Bus Ip4Address
property, replacing the existing hack.

Also add a few other missing properties noticed along the way.
