Add support for the _NET_WM_MOVERESIZE client message. This message
enables clients to initiate window moving or resizing. Toolkits like
Gtk3 use this message when the user drags a client-side decorated window
by its title bar. When Gtk detects that the window manager does not
support this client message, it uses a slow fallback implementation.

For these requests, we just close the window.

Maintain the _NET_DESKTOP_NAMES property on the root window.

_NET_NUMBER_OF_DESKTOPS:

We interpret this property as the number of noninternal workspaces.
Add and update the _NET_CLIENT_LIST property on the root window to
better comply with ewmh standards.
Information on this property can be found here:

> These arrays contain all X Windows managed by the Window Manager.
> _NET_CLIENT_LIST has initial mapping order, starting with the oldest window.

Windows that match the following criteria are floated by default:
- dialog, utility, toolbar, or splash windows,
- modal windows, or
- windows that have specified equal minimum and maximum size.

When the _MOTIF_WM_HINTS property of a window specifies it should have
no title bar, or no decorations at all, respond by setting the border
style of that container to BS_PIXEL or BS_NONE respectively.
This comes from the old Motif window manager. It was originally intended
to specify exactly what sort of decorations a window should have, and
exactly what sort of user input it should respond to. The EWMH spec
intended to replace Motif hints with _NET_WM_WINDOW_TYPE, but it is
still in use by popular widget toolkits such as GTK+ and Java AWT.
i3's implementation simply mirrors Gnome's Metacity. Official
documentation of this hint is nowhere to be found.
For more information see:

This ClientMessage can be used to estimate how big the window will be
before opening it. Java always sends the ClientMessage and checks the
atom that should be set by the window manager, but it seems that the
fallback code path has a race condition.
Let’s see if the situation gets better with this change. I have been
running this patch for about two weeks and have not seen any issues with
it.

_NET_WM_STATE_DEMANDS_ATTENTION indicates that some action in or with
the window happened. It's a weaker hint than urgency flag of WM_HINTS,
but some applications and almost all Qt applications use it instead of
WM_HINTS' urgency flag (one example is Skype).
This is mainly useful for the testsuite. The tests can wait until i3 processed
all X11 events and then continue. This eliminates sleep() calls which leads to
a more robust and faster testsuite.
This involves:
• Compiling with xcb-util instead of xcb-{atom,aux} (they merged the libraries)
• Not using xcb-{event,property} anymore (code removed upstream)
• Not using the predefined WINDOW, CARDINEL, … atoms (removed upstream)
• Using the new xcb_icccm_* data types/functions instead of just xcb_*
(for example xcb_icccm_get_wm_hints instead of xcb_get_wm_hints)
Also I refactored the atoms to use x-macros.
