yet another Xorg freeze exception round

[Julien Cristau <jcristau@debian.org>]

Hi again,

please unblock the following packages:

* libx11/2:1.1.5-2
new patch from upstream, fixes a memory leak

* mesa/7.0.3-6
debian/copyright update to the SGI FreeB License 2.0, which is free

* x11proto-gl/1.4.9-2
same as mesa

* xorg-server/2:1.4.2-7
same as mesa/x11proto-gl, plus one trivial bug fix for xvfb-run

* xserver-xorg-input-mutouch/1:1.2.0-2
one bug fix from upstream, reported there by a lenny user

Note that I didn't close the RC licensing bugs on xorg-server and
x11proto-gl, because some files (1 in glproto and 2 in xserver) are
licensed under the (non-free) GLX Public License.  While SGI has
relicensed their contributions under FreeB, which is now ok, it's not
clear whether the GLXPL still applies to contributions from other people
(the FSF thinks it does, while upstream has committed a patch to replace
the GLXPL with FreeB 2.0).

Thanks,
Julien
