Fix a bug in netlist where glibtop_netlist.number was never initialized to

Browse Source 
* Makefile.am:
	* cpu.c: (glibtop_get_cpu_p):
	* netlist.c: (glibtop_get_netlist_s):
	* netload.c: (glibtop_get_netload_p):
	* procmem.c: (glibtop_get_proc_mem_p):

	Fix a bug in netlist where glibtop_netlist.number was never initialized to 0
	(this resulted in a NULL pointer dereference in the network load feature
	of the multiload applet)

	* Add support for getting interface flags and packet counts even on interfaces
	without IP addresses (needed for the network load feature of the multiload applet)

	* Restore per-process limits in the !FreeBSD or __FreeBSD_version < 500013
	case

	* Add CPU interrupt time as IOWAIT to get support for the cpu load feature of
	the multiload applet.

	Patch from marcus@freebsd.org (Joe Marcus Clarke).
	Closes #168704.
