	Fix memory leaks.

	* system-settings/src/nm-system-config-hal-manager.c (get_type_for_udi):
	Free data returned from dbus method call.

	* system-settings/src/nm-polkit-helpers.c (check_polkit_privileges):
	dbus_g_method_get_sender() returns a duplicated string, free it
	when done.
	(check_polkit_privileges): Looks like policykit sometimes returns
	error and non-null return value, don't leak errors in that case.

	* system-settings/src/main.c (find_plugin): Don't leak existing
	plugin names.
	(load_stuff): Don't leak device list and list items.
	(have_connection_for_device): Don't leak connection list.

	* system-settings/plugins/keyfile/reader.c (read_one_setting_value):
	Free the data received from g_keyfile_get_*.

	* system-settings/plugins/ifcfg-suse/parser.c (READ_WEP_KEY): Free
	the key when the security object is updated.

	* src/supplicant-manager/nm-supplicant-interface.c (scan_results_cb):
	Free data returned from dbus method call.
	(iface_state_cb): Ditto.
	(add_network_cb): Ditto.
	(nm_supplicant_interface_add_cb): Don't make another copy of already
	duplicated object path.
	(nm_supplicant_interface_add_to_supplicant): Free the driver GValue
	when done.

	* src/supplicant-manager/nm-supplicant-config.c
	(ADD_STRING_LIST_VAL): Fix a memory leak.

	* src/nm-manager.c (free_get_settings_info): Free the allocated
	memory slice.
	(list_connections_cb): Free data returned from dbus method call.
	(system_settings_get_unmanaged_devices_cb): Ditto.

	* src/nm-device-802-11-wireless.c (device_cleanup): Free ssid.

	* system-settings/plugins/ifcfg-suse/shvar.c (svCloseFile):
	* system-settings/plugins/ifcfg-fedora/shvar.c (svCloseFile):
	* src/backends/shvar.c (svCloseFile): Free the duplicated content
