Martin Baulig 5fcfc95280 Added first kstat based implementation for Solaris 7.
1999-03-19  Martin Baulig  <martin@home-of-linux.org>

	Added first kstat based implementation for Solaris 7.

	* open.c (glibtop_open_s): Walk kstat list and save interesting
	kstats in the `server->machine'.

	* cpu.c: This can already provide `idle', `user' and `sys' with
	full SMP support.

	* swap.c: This can already provide `total', `used' and `free'.
