* Makefile.am:
	* netlist.c: (glibtop_get_netlist_s):

	Add support for FreeBSD 6-CURRENT.
	Use the more portable getrlimit to obtain process memory limits.
	Correctly determine process time.
	Stub out the procopenfiles() function (this is not yet implemented, however).
	Fix a nasty infinite loop and memory leak due to a forgot pointer increment.

	Patch from marcus@freebsd.org (Joe Marcus Clarke).
	Closes #168232.
