[PATCH] X server uses xwayland.conf instead of xorg.conf

[spitzak at gmail.com]

From: spitzak <spitzak at gmail.com>

This allows X applications to be run on wayland without having to
delete conf files needed to run the legacy X server on the same machine.

This is the only method I have found that will allow the built-in
default conf file to be used while an /etc/X11/xorg.conf.d directory
exists. There is no way to achieve this with switches to the server.

A file is needed to use the wlshm driver, this must now be named
$INSTALL/etc/X11/xwayland.conf. The instructions for running the
x server under wayland need to be fixed for this.
