services: xorg-wrapper: Support xorg server input rewriting.
This patch adds support for proper xorg server input rewriting. It uses the
lookup-package-direct-input procedure to configure the X server paths
dynamically, instead of always using the hard coded package. Something like
this is now possible:
(define other-mesa
(package-input-rewriting/spec `(("mesa" . ,(const other-mesa)))))
(xorg-configuration
(xorg-configuration
(server (other-mesa xorg-server))))
Without this patch the X server would still be configured with mesa (causing
version issues), and not with other-mesa (as per the input rewrite).
* gnu/services/xorg.scm (xorg-configuration-server-package-path)
(xorg-configuration-dri-driver-path, xorg-configuration-xkb-bin-dir)
(xorg-configuration-xkb-dir): New procedures.
(xorg-wrapper): Use them for dri and xkb paths.
