* fixed include path for generic Xresources in xdm's Xresources file
* fixed $XDMDIR in Xsession, so sys.xsession can be found
* sys.xsession: fixed syntax error in code, which reads
additional xdm scripts
* display-manager: also symlink Xstartup and Xreset in
/etc/X11/xdm (needed by lighdm)
* for now use again /etc/pam.d for xdm/xdm-np PAM files instead
of /usr/etc/pam.d (using the latter resulted in
"authentificataion failure" with lightdm)
