Fixed rebooting when init runs as /linuxrc

 	* Fixed "du" so it gives the same answers as GNU "du" (busybox du used 
 	    to count hard-linked files more then once).  Many thanks to 
 	    Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
-	* Removed /proc dependancies for init and free (while maintaining exactly
-	    the same functionality).  /proc takes up 90k of kernel space, so it is
-	    nice to avoid using it at all costs.
-	* init no longer tries to mount /proc (unless there is less the 1 meg free).  
-	    Use of /proc (or not) is policy that should be set up in /etc/fstab (or
-	    in hardcoded scripts), not in init.
