Merge branch 'master' into x-updates
dbus: minor update 1.6.14 -> .16 "fortify agility"
mesa: add GLES 1 and 2 support by default

The libs have just a few kilobytes and no additional deps.
mesa: bugfix update 9.2.1 -> .2

On 9.2.* we seem to be hitting a [problem] on Hydra
(unlikely to be fixed by this update),
although the tests run fine on my machine.

[problem] https://bugs.freedesktop.org/show_bug.cgi?id=67672
changes proposed for 'release-13.10' into x-updates

Conflicts (simple, taking whole higher/later versions):
	pkgs/development/libraries/gtk+/2.x.nix
	pkgs/development/libraries/mesa/default.nix
	pkgs/development/libraries/polkit/default.nix
perl: avoid --no-cpp-precomp on darwin, (close #1160)

Taken from https://trac.macports.org/ticket/38913
vcunat renamed the patch

Conflicts (trivial):
	pkgs/development/interpreters/perl/5.16/default.nix
darwin x11/opengl: only copy subset of files (close #1165)

Copy only the pc files related to X11 and OpenGL.

This should allow us to build our own version of libraries like
cairo without having the native ones be accidentally dynamically
linked in to things that depend on them.

Before this patch if we `dyldinfo -dylibs libpangocairo` we can
see that it was dynamically linked against the OS X (but seemingly
built against include files from the nix one, as we would get a
runtime complaint about missing symbols)
mesa: disable checkPhase for the time being

The problem doesn't seem serious and it only occurs on some HW.
However, it would be best to fix this before merging into master.
xorg-server: bugfix update 1.14.3 -> .4, including CVE

CVE-2013-4396, otherwise a few fixes, see
http://lists.x.org/archives/xorg-announce/2013-November/002352.html
xorg-server: remove now-upstreamed patch

I'm sorry I completely forgot to test the previous commit.
Also remove some long unused patch.
