We also remove support for WiMAX (now unsupported by NetworkManager),
and InfiniBand (Enterprise feature), and the use of
the deprecated NM_SETTING_WIRELESS_SEC property.
With help from network-manager-applet patches by Jiří Klimeš and
Dan Winship.

In addition to simplifying a bunch of places that were calling
nm_remote_settings_list_connections() +
nm_device_filter_connections(), this also ensures we filter out slave
connections everywhere (except when they are the active connection).

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.
