Except that this returns an invalid X11 handle.

There is only one queue at the moment, and if someone wants multiple
queues, it's probably not a good idea to hard-code queues as integers.

This improves readability a lot and prevent us from reinventing the wheel.

 - Remove useless system_VLCPath

Qt4 - Remove the qt-pl-showflags from preferences and put it in QSettings,because there is no way a normal being get it right.

      Remove the QDockWidget, this widget is clearly not what we want, since it is a Qt::Tool and stay above the video, it doesn't want to grow in the MI and it doesn't record correctly its size. Moreover, this force the GNOME/Cleanlooks hack that is boring on Xfce, KDE4 and e17.
      Fix the resize when the video is done.
      Fix the qt-start-minimize bug
      Rename a few functions and separate the code functions.
      Simplify a few resize/update call.

Qt4 - Launch the update every x days ( x being 14 days by default ). Check done just before the exec(). part 1.

Missing some cases that I could not test.
Also ffmpeg/chroma.c is locked, so I can but leave it broken.
Fix is for the remaining modules is obvious and the issue is easy to detect.
