With this commit, awesome prefers ARGB visuals over the screen's default visual.
This means that all our (visible) windows now can get an alpha channel that a
compositing manager can use for producing transparent windows.
The reason why this is done is to fix a bug. We are reparenting clients into
other windows. If one of these client window uses an ARGB visual, its
transparency would have no effect.

The window that is specified when a GC is created is used for two things. First,
it specifies which protocol screen the GC should be associated with. Second, it
specifies for which color depth the GC is valid.
Due to this second property, we have to use the systray window instead of the
root window. The systray window uses globalconf.default_depth.

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.

This removes the check for imlib2 which we no longer use. This also removes a
check for oocairo because we got that one twice for some weird reason.

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

They can and should now be done via gears.color instead. It was porting ever
since this was ported to oocairo anyway...

When awful.widget.launcher() is called with a string, it interprets it as the
path to an image and tries to load it. So why should we do the work of calling
image() ourselves if it can be done for us? ;)

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.

This implements objects in lua. Objects provide the signal functions that are
known from the C API ({dis,}connect_signal(), emit_signal(), add_signal()).

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).

With this patch, we track the number of objects that are alive for any class.
This information can be accessed via class.instances()
For example:
print("wiboxes", wibox.instances())
print("widgets", widget.instances())

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.
