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.

+# Description:
+#     We use elogind (standalone subset extracted from systemd) instead of
+#     systemd itself; so we need to initialize a systemd-like state.
+#
+# Note:
+#     Slackware has a tmpfs mounted on /run (see rc.S).
+#
+
+# The systemd/elogind state directory:
+mkdir -p /run/systemd
+chmod 0755 /run/systemd
+
+# Toplevel directory for runtime user session data:
+mkdir -p /run/user
+chmod 1777 /run/user
+
+# Elogind uses cgroups to organize processes like mapping PIDs to sessions.
+#  Elogind's cgroup hierarchy isn't associated with any resource controller
+# ("subsystem") so we must create it manually:
+mkdir -p /sys/fs/cgroup/elogind
+mount -t cgroup -o none,name=elogind elogind /sys/fs/cgroup/elogind

+xorg-server-xvfb: xorg-server-xvfb (virtual framebuffer X server)
+xorg-server-xvfb:
+xorg-server-xvfb: Xvfb is an X server that can run on machines with no display hardware
+xorg-server-xvfb: and no physical input devices.  It emulates a dumb framebuffer using 
+xorg-server-xvfb: virtual memory.  The primary use of this server is intended to be 
+xorg-server-xvfb: server testing.  The mfb or cfb code for any depth can be exercised
+xorg-server-xvfb: with this server without the need for real hardware that supports the
+xorg-server-xvfb: desired depths.  A secondary use is testing clients against unusual
+xorg-server-xvfb: depths and screen configurations.
