[xserver: PATCH] config/udev: allow passing arbitrary configuration via 'ENV{x11_options.$opt}'

[Sergei Trofimovich]

It is convenient to play with mouse/touchpad changes at runtime.

    ENV{ID_INPUT_MOUSE}=="?*", ENV{x11_options.Emulate3Buttons}="True"
    # replug the revice to see immediate effect

and consistent with hal's configuration scheme.
