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).

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().

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.

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)

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.

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.

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.

The systray bases its extents on the size of the wibox that it is contained in.
No idea how this is supposed to work when the systray doesn't get the full size,
but in a vertical wibox, using <height of wibox> * <number of icons in systray>
certainly doesn't work for computing the size.
The fix isn't hard: Check the wibox' orientation when drawing and base our
calculation on its width if its orientation is different from East.

Previously, if a client had nofocus == true, it wasn't unminimized if sth tried
to focus it. Also, if this client had the WM_TAKE_FOCUS protocol, the focusing
would fail since it's an error to set the input focus to an unviewable window.
For consistency, this also moves the code that sets a client's minimized
property to false into client_unban() since it doesn't make sense to have a
minimized client unbanned (i.e. visible).
