To apply the shape of a client, we have to create an image and draw the
shape we want to it. Since clients can be quite large, we have to make
sure that we do not keep this image alive unnecessarily long.
The code in awful.client.shape.get_transformed() however needs another
temporary surface in case the client has its own shape and another one
was set in Lua (side note: currently the code also creates this extra
temporary surface if the client does not have its own shape; that might
be worth fixing). This temporary surface is then used as the source of a
cairo context to draw it to the image that will be used as the client's
final source.
After we are done, the temporary surface is still kept alive since it is
the current source of the cairo context. The cairo context in turn is
only freed when Lua's garbage collector collects it, which may take
quite a while.
Improve this by setting a different source to the cairo context. Thus,
it now releases the temporary surface as soon as possible and it is only
allocated for a short time.

This function queries the shape of a client and then does something with
it. This commit makes sure the image is finished afterwards, which means
that most of its memory is released immediately instead of waiting for
the garbage collector to collect it.

The functions awful.client.shape.update.bounding and .clip handle both
the client's shape and the shape set by Lua. However,
awful.client.shape.update.all only handles the shape set by Lua and
ignores the client's own shape. This can easily be noticed with xeyes.
When update.all ran last and you move around xeyes, the wallpaper behind
it is moved along, because it is not actually outside of the window.
Fix this by partly reverting 1a5f6b7ad2 and having update.all just
call the other two functions again.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

A nil-value is no longer simply passed through, so this has to do some "special
things" to work properly.
