Subject: [package] base-files: 	- add sysupgrade support for keepfile hints 
 	* introduces /lib/upgrade/keep.d/ for per-package keepfile lists 
 	* introduces /etc/sysupgrade.conf for user defined keepfile hints 
 - prime /lib/upgrade/keep.d/base-files-essential to keep sysupgrade usable
 for images without opkg 	- change sysupgrade to build the keepfile list
 from /lib/upgrade/keep.d/, /etc/sysupgrade.conf and 	  opkg
 list-changed-conffiles
