See <http://www.x.org/wiki/Development/Security/Advisory-2014-12-09/>

* gnu/packages/xorg.scm (xorg-server): Update to 1.16.2.901.  Move mesa,
  resourceproto, scrnsaverproto, and xf86driproto from inputs to
  propagated-inputs.  Add dri3proto and presentproto to propagated-inputs.
  Add eudev and libxshmfence to inputs.  Add a 'pre-configure' phase instead
  of modifying the 'configure' phase.  Adapt substitution that avoids trying
  to 'mkdir /var' to build system changes.

* gnu/services/xorg.scm (xserver.conf): Add xf86-input-evdev ModulePath line.
