Handle the EWMH atom _NET_WM_DESKTOP.
We already claim _NET_WM_DESKTOP support in _NET_SUPPORTED since around 2009,
but haven't actually done anything with it. However, especially pagers like
gnome-panel rely on this property to be updated and many tools, like GTK, want
to use the corresponding client messages to make a window sticky, move it
around etc.
This patch implements full support according to the EWMH spec. This means:
* We set the property on all windows when managing it.
* We keep the property updated on all windows at all times.
* We read and respect the property upon managing a window if it was set before
mapping the window.
* We react to client messages for it.
* We remove the property on withdrawn windows.
Note that the special value 0xFFFFFFFF, according to the spec, means that the
window shall be shown on all workspaces. We do this by making it sticky and
float it. This shows it on all workspaces at least on the output it is on.
Furthermore, the spec gives us the freedom to ignore _NET_WM_DESKTOP when
managing a window if we have good reason to. In our case, we give window
swallowing a higher priority since the user would likely expect that and we
want to keep placeholder windows only around for as long as we have to.
However, we do prioritize this property over, for example, startup
notifications.
This disables the default leak-check-on-exit behavior which reports a
bunch of leaks that are only leaks while exiting, at which point they
don’t matter, because the operating system will clean up the memory our
process used.

Comply with documentation: 'workspace' token in 'assign' command
According to the User's Guide [1], an `assign` command allows a
`workspace` token after the selector, as an alternative or in addition
to the unicode arrow `→`. In reality, however, the `workspace` token is
not recognized.
Example:
assign [class="Firefox"] workspace "1: Browser"
should assign Firefox windows to workspace `1: Browser`, but the the
browser window appears on a new workspace called
`workspace "1: Browser"` instead.
With this fix, both `→` and `workspace` are recognized (and ignored)
after the selector.

i3bar: explicitly set cursor using libxcursor if available
Even if the X11 root window cursor is not set up correctly for some
reason, with this fix, users should at least see the correct cursor when
the pointer is over i3bar.
This fixes race conditions, for example when i3bar gets reconfigured
after the available outputs change. In that specific case, i3bar sends a
ConfigureWindow request (see
https://github.com/i3/i3/blob/b5693d6fb33ad29337e4187a2db4a2618ea8fb4c/i3bar/src/xcb.c#L376)
which normally is turned into a ConfigureRequest that i3 largely
ignores, only the dock client’s height is considered (see
https://github.com/i3/i3/blob/b5693d6fb33ad29337e4187a2db4a2618ea8fb4c/src/handlers.c#L390).
Turning ConfigureWindow into ConfigureRequest is only done when the
SubstructureRedirect event mask is set, and because we temporarily
removed _all_ events from our mask, the ConfigureWindow request went
through unmodified.
This in turn lead to the i3bar client window (not its decoration frame)
being positioned at e.g. y=1304, whereas dock client windows should
always end up at x=0 y=0 within their decoration frame. The result of
the i3bar client window being out of the visible space was either a
black i3bar or graphics corruption.
This also fixes issue #1904, I think. I couldn’t reproduce issue #1904
specifically, but when i3bar is in the misconfigured state, it will
receive a VisibilityNotify event, telling i3bar that it is obscured.
This would explain why i3bar sent a SIGSTOP in issue #1904.

the fallback behavior of using the focused window took over.
For con_id, id and window_type we now reject incorrect values with

Use 32-bit visual by default if available.
With this patch, we use 32-bit visuals per default whenever it is

Before this patch, we already used 32-bit depth for containers with
a window that uses 32-bit. However, this means that we didn't use
32-bit for split parent containers on which decoration is drawn.
For 32-bit windows using transparency, this caused a graphical glitch
because the decoration pixmap behind it would show through. This
behavior is fixed with this change.

Don't create a pixmap for CT_ROOT and CT_OUTPUT containers.
Such containers never require a pixmap anyway. In particular for the __i3

Until now, this error was silently ignored due to the fact that we did not

would cause a crash because we'd try to create a surface for a pixmap
which doesn't exist.
