xwm: Support _NET_WM_STATE_FULLSCREEN
We can now handle fullscreen X windows. X clients request to go fullscreen buy sending a _NET_WM_STATE client message to the root window. When that happens we call into the shell interface and asks the shell to make the surface fullscreen. The shell will then resize the window, which causes the X wm to configure the X window appropriately. Make sure we ignore configure requests from fullscreened clients and send out the synthetic configure notify as required in that case. Finally, inspect _NET_WM_STATE before mapping so we can handle initial fullscreen correctly.
