[PATCH] X server talking to wayland 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.

Currently you must use an xwayland.conf file if the wlshm x driver is
necessary.

I patched the xorg server rather than the xserver weston module
because:

 1. It is already patched to take a "--wayland" switch.

 2. A patch was required to stop it from reading xorg.conf.d. This
version also prevents that if --configdir is given, a more complex
patch could be used if there is concern about this being an incompatable
change.
