[ClutterStageX11] Remove the handling_configure flag

Browse Source 
Since Clutter changed to using a layout scheme the handling_configure
flag no longer works because the allocate method is not invoked
immediately during the call to set_size from the ConfigureNotify
handler. However it is also no longer neccessary because the resizes
are effectively batched up until a relayout is run so it won't cause
an infinite loop of resize and notify events anyway.

because the window will be resized to xwin_width and
xwin_height so the above test will prevent it from resizing
the window a second time. However if the stage is resized
multiple times without the events being processed in between
(eg, when calling g_object_set to set both width and height)
then there will be multiple ConfigureNotify events in the
queue. Handling the first event will undo the work of setting
the second property which will cause it to keep generating
events in an infinite loop. See bug #810 */
