remember to configure vlc with --with-ffmpeg-zlib

* the prime manage thread now runs every .1 sec instead of .3,
  this might improve response sometimes.

fix it... (it should be annoying only with TS, you may have dead program
entry).

has been cropped.

* Updated TODO list

* modules/stream_out/transcode.c: when overlaying subtitles, duplicate frames if they are referenced by the decoder.

* video_chroma/i420_rgb.c: disable RV24 support (which was assuming 32 bits per pixels).

  (but *very* unlikely) segfaults

* stream_out/transcode.c: deinterlacing works again.

* modules/audio_filter/converter/dtstofloat32.c: added implementation for the new audio filter architecture.
* codec/dts.c: bug fix.
* codec/araw.c: added more PCM formats to the encoder.

* modules/audio_filter/converter/a52tofloat32.c: added implementation for the new audio filter architecture.

* modules/stream_out/transcode.c: respect input requested by encoder.

  + correct cropping of the decoded video when specified.
* stream_out/transcode.c: make sure the size of the encoded video is at least a multiple of 2.

* modules/demux/ogg.c, modules/demux/mkv.cpp:
  - store the vorbis/theora/speex headers in fmt.p_extra.
  - this change simplifies the code quite a bit and is a lot cleaner.
* modules/codec/vorbis.c, theora.c, speex.c, flac.c:
  - get the headers from fmt_in.p_extra or from the bitstream if empty.
* modules/mux/ogg.c:
  - recontstruct the headers from fmt.p_extra.
