This means NetObject is now obsolete and can be removed.
There was a GtkSizeGroup that the mobile settings used, but it isn't clear if
this is still relevant. It should be added back later if found to be (this code
is likely to be removed to make way for a dedicated mobile panel).
This one did not require any specific changes beyond moving
the struct definition to the .c file, and removing the old
style GObject boilerplate. Remarkably easy.
When we're finalizing, the remote settings instance might already be
gone and thus we can't list connections. In particular this happens at
panel finalization resulting in the following warning:
libnm-glib-CRITICAL **: nm_remote_settings_list_connections: assertion
'NM_IS_REMOTE_SETTINGS (settings)' failed
because cc_network_panel_dispose() unrefs the remote settings object
before all the NetDevice instances are finalized.
Since we only need to list connections on finalize to disconnect a
signal we can instead use g_signal_connect_object() and keep the
connections that we're keeping track of in a hash table instead of
g_object_set_data().

Rename NetDeviceWired to NetDeviceEthernet, but split out most of the
code into a new NetDeviceSimple superclass that can later be used for
other device types that we provide only minimal UI/support for.
