	* libnm-glib/Makefile.am
	  libnm-glib/nm-dhcp4-config.c
	  libnm-glib/nm-dhcp4-config.h
		- Handle DHCP4 config objects exported by NM over D-Bus

	* libnm-glib/nm-device.c
	  libnm-glib/nm-device.h
		- Add a 'dhcp4-config' property

	* libnm-glib/libnm-glib-test.c

		- Treat dhcp4-config object as an object path at the D-Bus interface so
