win: don't ignore SHADOW_STALE flag on unmapped windows
Previously all image stale flags are ignored when processing an unmapped
window. If a window gains a shadow during its fading out transition, the
shadow flag will be set, but shadow won't actually be generated, causing
a NULL pointer dereference during render.

Fixes #239

events: don't call win_get_name for logging
win_get_name _updates_ the name of the window by querying the X server,
thus potentially changes the behaviour of the compositor when logging is
turned on (e.g. we could fail to detect window name changes, because the
name was blindly updated in a logging call without handling the name change).

We shouldn't do that.

Make potentially window destroying functions take simple pointers
Instead of pointer to pointer. The two level of pointers were used to
inform the caller the window has been destroyed (pointer set to NULL).

Now, destruction of windows are now signaled by the return value, which
is marked `must_use`.

Problem with taking pointer to pointer is that they tends to pollute the
function signatures a little bit. And we are not using it well anyways.
A lot of the callers passes pointers to local variables to those
functions, so the information about window destruction doesn't actually
bubble up. So, we switch to use just one level of pointers instead.
