		- (nm_utils_garray_to_string): remove; NM was the only user and doesn't
			export anything that needs to be converted with this function

	* src/dhcp-manager/nm-dhcp-manager.c
		- (garray_to_string): convert a byte array to a UTF-8 string with
			minimal validation; the DHCP client sends it in ASCII anyway
		- (get_option, copy_option): use garray_to_string()
