Olivier Fourdan 5171e35a97 xwayland: Add a setting to disable selected X extensions
The X server, including Xwayland, can be compiled with different X11
extensions enabled at build time.

When an X11 extension is built in the X server, it's usually also
enabled at run time. Users can chose to disable those extensions at run
time using the X server command line option "-extension".

However, in the case of Xwayland, it is spawned automatically by the
Wayland compositor, and the command line options are not configurable
by users.

Add a new setting to disable a selected set of X extension in Xwayland
at startup, without needing to rebuild Xwayland.

Of course, if Xwayland is not built with a given extension support in
the first place (which is the default for the security extension for
example), that option has no effect.
