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.

These signals also contain the x and y coordinate of the event which the
capi.button()-based signals can't provide.

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.

All the APIs that accept both an image and a cairo surface now only accept cairo
surfaces. Images are gone.

For compatibility one can now set an imagebox' .image to both a cairo surface
and an image object. The image will automatically be converted into a cairo
image surface.

The last commit caused some lua errors and reading a wibox' type property
didn't work. This should all be fixed now.

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.

Function imlib_create_cropped_image() from imlib2 doesn't initialize
buffer for new image, so if we use crop bounds bigger than original ones
we need to erase garbage from derived image.
This bug produced colorful pressed buttons (FS#516, FS#822).

If we called the widget layout for x widgets, but the layouts returned less
geometries than this, we silently ignored the left-over widgets. If the layouts
returned more geometries, we crashed.
Fix this by verifying that the number of widgets and the number of geometries
are equal. If they are different, we use the smaller of the two.

While drawing the wibox, the C core builds up a list of widgets and their
associated geometry. This list consists of widget_node_t objects and is
constructed like this (This is from luaA_table2widgets()):
widget_node_t w;
p_clear(&w, 1);
w.widget = luaA_object_ref_item(L, idx, -1);
widget_node_array_append(widgets, w);
After we are done with this list of widget nodes, it is freed via
wibox_widget_node_array_wipe(). However, wibox_widget_node_array_wipe() passed
"&w" to luaA_object_unref_item() while it should have used "w.widget" (which is
what was returned from luaA_object_ref_item()). This made the unref fail and the
wibox was carrying around a reference to this widget forever. This was
effectively a memory leak.

When setting a new widgets table, the wibox obviously should drop its reference
on the old widgets table.

The only string format for colors that we now support are #rrggbb and #rrggbbaa.
All other strings will cause errors.
Thanks to this, color_init_cookie_t can be removed. There won't be a request to
the X server for transforming named colors any more and so there won't be a
cookie. This means that color_init_reply() has to be removed, too.
