[PATCH] Wayland X server uses xwayand.conf instead of xorg.conf

(sorry for duplicate I forgot to do reply-all)

Yes the reason I need an xorg.conf is that I need the wlshm driver. 
According to the documentation the other drivers work automatically, so 
if it is possible to detect this then there should be no need for a file.

However this does not fix the problem this patch is addressing. Even if 
*no* xorg.conf file is needed, it is impossible to tell xwayland to not 
use an existing xorg.conf file, such as one needed to run legacy X on 
the same machine. The text in this then screws up xwayland and it does 
not run.

An alternative to my patch is to change it to *never* read the config 
file. However this seems unsafe, for instance currenlty the wlshm driver 
cannot be made to work. Also even if all the driver/screen problems are 
fixed, it appears xorg.conf files are needed to fix events for Xlib 
programs. In one machine I have this is the only way to get two 
different mice to have different button assignments.
