Remove file context aliases and update file context paths to use the /run filesystem path.
Add backward compatibility file context alias for /var/run using applications like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783321
Lock files are still seated at /var/lock
Remove unneeded permissions to read user content from the
xserver module (xserver and xdm domains).

On Arch Linux, /usr/bin/Xorg is only a shell script which executes
/usr/lib/xorg-server/Xorg.wrap, which is a SUID binary wrapper around
/usr/lib/xorg-server/Xorg.
Even though Xorg.wrap is not a full X server, it reads X11 configuration
files, uses the DRM interface to detect KMS, etc. (cf.
http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/xorg-wrapper.c?id=xorg-server-1.18.0
for more details). Therefore label it as xserver_exec_t.
This makes the following AVC appear:
denied { execute_no_trans } for pid=927 comm="X"
path="/usr/lib/xorg-server/Xorg.wrap" dev="dm-0" ino=3152592
scontext=system_u:system_r:xserver_t
tcontext=system_u:object_r:xserver_exec_t tclass=file
Allow /usr/bin/Xorg to execute Xorg.wrap with a can_exec statement.
On Gentoo, slim files are not in /var/run/slim, but directly in
/var/run. All names start with slim though, so changing the expression
to match those as well.
There is already a file transition in place (xdm_t writing files in
var_run_t -> xdm_var_run_t) so that needs no further changes.

In Debian, this initscript is creating both /tmp/.X11-unix and
/tmp/.ICE-unix. This allows the directory to transition to the context
defined in the filecontext.
Introduce the substitutions for the /usr/local/lib* locations (towards /usr/lib)
and /etc/init.d (towards /etc/rc.d/init.d).
Update the file contexts of the translated locations.
Rebased (collided with Guido's patch for commenting within the
file_contexts.subs_dist file) since v3.

Now that we have file_contexts.subs_dist, translations that were put in the file context definition files can now be
cleaned up.
Differences from v1:
- removes a few duplicate entries in the libraries.fc file, and
- removes the contrib references

When starting the X server from the console (using the startx script
that is being shipped with package xinit from X.Org), a few more
permissions are needed from the reference policy.
The label is for a file created by the startx script (from X.Org) and
the module being requested is ipv6 (which can be disabled by other
means).
