x11: implement --fs-screen properly, separate old code path
Try to get the "new" code path (using NetWM/EWMH) free of hacks done for the sake of old WMs or the no-WM case. Implement --fs-screen using _NET_WM_FULLSCREEN_MONITORS.

This option does not work properly with all window managers.

``all`` in particular will usually only work with
|

``--x11-fstype=-fullscreen`` or ``--x11-fstype=none``, and even then

only with some window managers.

This option does works properly only with window managers which

understand the EWMH ``_NET_WM_FULLSCREEN_MONITORS`` hint.
