Hello,

openSUSE started to split the distribution provided configuration files 
from the changes the user makes. We have, similar to systemd, a 
vendor directory below /usr with the distribution configuration files 
and applications will merge the configs at start. For this, we developed 
libeconf to make that part easier.

This patch implements libeconf support for util-linux and adds a
configure option to specify the vendor directory below /usr. This is
fully optional, without libeconf the current behavior will stay, and
even with libeconf support, if there is no vendor directory, the
tools will behave as of today.

/etc/login.defs and /etc/default are read with this patch through
libeconf. As there are at minimum 3 projects using /etc/login.defs
and two (shadow and Linux-PAM) the two biggest consumers accepted
this change already quite some time ago, it would be nice if 
util-linux would also accept and merge the patch to not behave
different than the rest. 

Thanks,
   Thorsten
