* include/vlc_filter.h, vlc_video.h, src/video_output/vout_subpictures.c: new simpler and more powerful text renderer api.
* modules/misc/freetype.c: rewrite to the new api + outputs YUVP subpicture regions now.

* Fix udp->tcp rollover when using multicast in rtsp. now bail after 36 seconds in case of multicast, .9 seconds otherwise. Bail after 3secs of no longer receiving data (multicast or unicast).

* dirty patch to tell vlc (on osx) that it needs -liconv when it links to libcdio. This should be fixed in the libcdio pkgconfig, but i'm tired of figuring out how to patch libcdio to do this.

   doing something

- Some cleanup

  reuses a given picture_t without allocating a new one.
* modules/video_output/picture.c: New --picture-height and width options
  to do the scaling in the vout thread. Misc bug corrections.
* modules/video_filter/mosaic.c: Less overhead.
* modules/codec/ffmpeg/video_filter.c: Do the scaling before the conversion
  in case the original size is bigger than the destination.

* modules/codec/ffmpeg/video.c: assume (M)JPEG YUV420 is the same as I420 (we could convert to have the exact chroma but that would be slower).

* modules/access/dshow: flush the capture pin's buffers when the capture filter is stopped (instead of doing it in the pin's destructor).

- EA ADPCM decoder (Maxis games)
(- corner case memleak in adpcm decoder)

  Mac OS X

- activate (make visible) as soon as embedded into a container, no longer wait for container to do the activation

This fixes an annoying Internet Explorer optimization which would make the activex control invisible till a user moves the mouse over it

Fix mpeg ps time output, making it seekable.  There may still be an error in there -- a test file reports 11:57 on VLC, 15:42 minutes on WMP, though it plays OK on both, seekable to the end.
