* src/video_output/vout_intf.c: new vout_ControlWindow() function.

* modules/gui/wxwindows/video.cpp: implement vout_ControlWindow().
* modules/video_output/directx/events.c, modules/video_output/x11/xcommon.c:
  + call vout_ControlWindow() when resizing in embedded mode.
  + implemented a VOUT_REPARENT/CLOSE mode in Control() so the interface can signal that it closes its video window.
