Wayland: needs recompiled mesa, xorg-server and addition of elogind.

- Slackware's mesa package was recompiled against wayland.
- Slackware's xorg-server package was recompiled against wayland; note that
  this package obsoletes the original xorg-server-xephyr, xorg-server-xnest
  and xorg-server-xvfb packages because the new xorg-server package is
  all-in-one.
- New package elogind is the systemd project's 'logind', extracted to be
  a standalone daemon (quite similar to the 'eudev' package we already have
  in Slackware).  An implementation of the logind dbus protociol is required
  by kwin_wayland.  At the moment, there is no other option than elogind
  until the ConsoleKit2 developers implement the protocol.

+Subject: [PATCH] Fixes to user and session saving
+
+* src/login/logind-dbus.c (method_create_session): No need to save
+  session here, as session_send_create_reply will do it.
+* src/login/logind-session-dbus.c (session_send_create_reply): On the
+  other hand we do need to save the user here, so the file marks them as
+  being active.
