Open some windows, select a layout which does something (=not floating) and
restart awesome. It's likely that it will crash during the shutdown.
The reason is that awesome cleans up various state before going down. This is
mostly all the lua state. However, drawin_wipe, which is called for cleaning up
after a drawin, dared to emit a sigal which then let various lua code run which
had access to objects which were already destroyed.
Various bad things can happen this way, in this situation it was a crash when an
already-destroyed client was resized.
The fix is to move the signal out of drawin_wipe. It doesn't belong there
anyway. Instead, property::workarea should be emitted when the drawin's visible
property changes as this is when the workarea changes, too (screen_area_get()
only looks at visible drawins).

xcb-util is now split into several repositories since 0.3.8. This
release also cleaned up the API a lot, thus update the code
accordingly.

This fixes a crash when the opacity of a not-visible drawin is changed. This
happened because we got a PropertyNotify for our own change of _NET_WM_OPACITY
and then tried to set the drawin's opacity to this new value.
However, the drawin was only reachable through globalconf.drawins and wasn't
ref'd in lua. This means that the luaA_object_push() call in
property_handle_net_wm_opacity() didn't find the drawin and instead pushed a
nil. This then later caused an unprotected lua error in window_set_opacity().

Both client_isvisible() and client_maybevisible() where almost exclusively
called with the client's screen as their second argument. Remove this second
argument and let these functions instead always act on the client's screen.

There isn't much point in the screen property of a drawin because the geometry
already defines on which screen the drawin is.
The biggest chunk of changes from this is due to removing the functions
drawin_detach and drawin_attach which where called when the screen property was
set/unset.
The code from drawin_detach is moved into drawin_set_visible and drawin_wipe.
drawin_attach is moved into drawin_init.

Thanks to a recent commit, a drawin's window will always be a valid and existing
window. This means we can remove all the code which checks this before doing
something.

We don't need an up-to-date pixmap and cairo surface for a drawin which isn't
visible. Thus, only bring those up-to-date when the drawin is visible.

Instead of creating/destroying a window whenever the drawin is attached/detached
from some screen, a window is now created when the drawin is created and it
isn't destroyed until the drawin is garbage collected.
Since we can now safely assume that a drawin always has a associated window,
this should make it possible to simplify some stuff.

When a client sets WM_NAME (client->alt_name) but doesn't set _NET_WM_NAME
(client->name), we give alt_name to lua when c.name is used. However, we still
emitted property::alt_name instead of property::name to lua. Obviously, this
breaks stuff.
(The same applies to client->alt_icon_name)
I noticed this via feh whose tasklist entry wasn't refreshed when multiple
images were displayed and I switched to the next one.

Before this commit, c:tags(tags) and t:clients(clients) first removed all
tags/clients and then added the new one.
This is now changed into only removing the tags/clients that have to be removed
and leaving the others in place. Hopefully, this avoids all kinds of weird
issues which we had.

In commit 3dbf89c I removed a client_unban() in the code path for focusing
clients. The idea was that client focusing is now done after rebanning, so that
it should already be visible by the time this code is executed.
However, minimized clients obviously don't get unbanned, So we have to call
client_unban() here to make sure the client is unminimized.

The lua code could keep a reference to out cairo surface for a drawin after it
was destroyed. So make sure the surface is finished before the associated
drawable is destroyed.

We actually have to set a proper background color on all our drawins, else the
default black will "flicker through" while the window is drawn.

Instead of immediately setting the X11 input focus when client.focus is assigned
something, we now just remember that we'll have to do something later. The focus
is then set in the next prepare call by libev (= after the current main loop run
is done).

When we receive a DestroyNotify, we have to unmanage the client. However, we
were just informed that the window was destroyed, so it doesn't make sense to
try to do "something" with the window.
This commits fixes some errors from the X server (which we ignored, but still
they are gone now).

Lua now has access to a cairo surface via drawin.surface. When the drawing to
this surface is finished, it should call drawin:refresh() to make the result
visible.

It is perfectly valid for a cairo surface to delay the actual. This is mostly
done in situations where it speeds stuff up. Since we want our drawing to be
visible, we have to flush the cairo surface when we are done drawing.

All windows which use globalconf.default_depth must also have a backpixel,
borderpixel and colormap set when they are created. Without this, all these
xcb_create_window() calls would fail when globalconf.default_depth is no longer
the screen's default depth.

alloca() allocates stack space. The image that we were producing is possibly
huge which means that we were asking for e.g. 9MiB of stack space. This is not
really a good idea and caused crashes.
Fix this by using heap memory instead.
