* modules/video_filter/swscale/*: new resizing/chroma conversion video filter based on MPlayer's swscale module.
  (not enabled in configure.ac yet as it may have problems building on some platforms)

   (cause latest BeOS gcc doesn't do it by default anymore)

* src/video_output: fixed a CPU heating loop in pause mode (fixes the problem with fast user switching on win32).

  - switch to access_demux module for raw video/audio streams.
  - massive cleanup and simplifications.
  - a bunch of fixes.

* modules/access/dshow: simplification (video inversion is now handled in the rawvideo codec/packetizer).

* modules/video_output/directx/events.c: use a different window class for the video sub-window so the background color doesn't get messed-up with.

* modules/video_output/x11/xcommon.c, modules/video_output/directx/directx.c: when we invert the YV12 picture buffer chroma planes, we need to report a I420 chroma.

 modules/codec/ffmpeg/video_filter.c, modules/audio_filter/format.c, normvol.c: added Id svn keyword.

* src/video_output/vout_intf.c, modules/video_output/opengl.c: we do really need these, so please don't remove them again.

* modules/stream_out/transcode.c: use picture ring buffers to avoid leaks due to decoders not releasing pictures properly and to avoid uncessary mallocs.

* modules/gui/wxwindows/video.cpp: reverted change to re-use the video window as it doesn't work well on wxGTK.
