update-alternatives-cworth: use /usr/lib/opkg/alternatives directory instead of /usr/lib/ipkg/alternatives
* It's usefull to make it compatible with u-a script in opkg package
* Old entries are merged to new directory in quite verbose postinst
script
* If entry exists only in old its moved
* If entry exists in both the one with more lines is used
* The one with less lines is not used and warning is shown
* If they have the same number of lines diff is checked
* If they are the same, old one is ignored
* If they are different, old one is ignored and warning is shown
