Removed some un-used code from CVS. We can always resurrect this later if
someone feels they want to work on it. Gone are the old perl ihost which
isn't needed now, winhost which is broken and shows no sign of being fixed,
and DBReporter. If someone wants to revive them, I'll undelete them :-)

Now gets CPU stats, mem and swap stats. The problem with swap stats is that it needs to be
either suid root, or setgid kmem. I've assumed the latter since thats safer, and so it needs to be
setgid kmem to work now. The program however runs as a mortal except at the very moment it needs the
permissions where it gets them, and then releases them one system call later.
