Ray Strode c424458c93 xwayland: default to local user if no xauth file given. [CVE-2015-3164 3/3] 
Right now if "-auth" isn't passed on the command line, we let
any user on the system connect to the Xwayland server.

That's clearly suboptimal, given Xwayland is generally designed
to be used by one user at a time.

This commit changes the behavior, so only the user who started the
X server can connect clients to it.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
