* libnm-util/nm-connection.c
	  libnm-util/nm-connection.h
		- (nm_connection_compare): accept compare flags and pass them to the
			setting compare function

	* libnm-util/nm-setting.c
	  libnm-util/nm-setting.h
		- (nm_setting_compare): accept compare flags; ignore properties that are
			marked fuzzy

	* libnm-util/nm-setting-connection.c
	  libnm-util/nm-setting-wireless.c
	  libnm-util/nm-setting-ppp.c
	  libnm-util/nm-setting-wired.c
		- Mark some setting properties as ignorable when doing a fuzzy compare

	* src/nm-device.c
		- (device_activation_precheck): use exact compare
