21c8c925d8 * With Rudolf's information about relocating overlays, I changed the way memory
is managed for those bitmaps:
  - the shared client memory mechanism is used to allocate a small overlay_client_data
    structure that contains the actual buffer and a semaphore that you have acquire in
    order to access it.
  - LockBits()/UnlockBits() now have a function: you need to call them before accessing
    the overlay buffer, and you need to keep that lock until you're done with it.
* The overlay cookie is now an extra member of the ServerBitmap class.
* Removed fInitialized from ServerBitmap - IsValid() now just checks the buffer associated
  with the bitmap.
* ViewLayer::Draw() will now handle overlay bitmaps specially and will draw the overlay
  color instead of any contents (this is currently in ugly pink, but will become some
  dark color later on).
* All what's missing from actually being able to use overlays now is to configure
  them so that they are shown on screen. VLC will now show an empty pink window when
  overlay video is enabled.
