* Makefile (confdir/clients.conf): Tighten permissions to "u=rw".
  (install-server): Set mode of "/etc/mandos/clients.conf" to
                             "u=rw".
  (install-client): Set mode of "/etc/mandos/plugins.d" to "u=rwx".
  (uninstall-client): Also remove "/usr/lib/mandos/plugins.d/usplash",
                "/usr/share/initramfs-tools/scripts/local-top/mandos",
                      and "/etc/keys/mandos".
  (purge-server): Also remove "/var/run/mandos.pid".

* initramfs-tools-hook: Use "install" instead of "mkdir".  Change
                        owner of "/lib/mandos/plugins.d" and key
                        files.  Bug fix: do not repair permissions of
                        "/lib/mandos/plugins.d".  Bug fix: Really
                        avoid deliberately unreadable files and/or
                        directories.

* mandos-keygen (umask): Changed to "077".
