change

  - chroma + resizing video filter (using the filter_t architecture).
* modules/codec/ffmpeg/*:
  - cleanup + small updates.
* modules/codec/speex.c, theora.c, vorbis.c:
  - got rid of pf_header() in the encoder.
  - store the headers in fmt_out.p_extra (this will break the ogg muxer for now).
* modules/codec/libmpeg2.c, modules/codec/ffmpeg/video.c:
  - added a p_dec->b_pace_control field to signal if the decoder is allowed to drop frames.
* modules/stream_out/transcode.c:
  - heavy cleanup.
  - re-use video decoder modules and got rid of the duplicated ffmpeg video decoder.
  - use video filters for chroma conversion and resizing.
  (a few things are broken now like deinterlacing but I'll repair them asap).

 if we find them. (Avoid dropping the first frame).

first go through the h264 packetizer that will convert avc1 into a
proper annexe B stream (untested).

  + small fix for --ffmpeg-workaround-bugs.
  + new --ffmpeg-vismv option to visualize motion vectors.

* modules/stream_out/duplicate.c: small coding style changes.
* modules/stream_out/transcode.c:
  + Forward the aopts{foo=bar,etc..} and vopts={foo=bar,etc...} options to the encoders.
  + Got rid of the ffmpeg encoder specific options.
* modules/codec/ffmpeg/*:
  + Changed the encoder options to normal config options.
  + Parse the options forwarded by transcode.
* include/vlc_codec.h:
  + encoder_t cleanup.
  + include a "sout_cfg_t *" in encoder_t to allow passing options.

 than just the "SMI " one).

 field and a few BLOCK_FLAG_*.

* modules/codec/ffmpeg/video.c: another fix for switching postproc on the fly.

* modules/codec/ffmpeg/video.c: another fix for post-processing.

 * pass bit per pixel info on to decoder
modules/demux/avi/libavi.h:
 * add 1 as fourcc for msrle
module/codec/ffmpeg/video.c:
 * pass bit per pixel info to libavcodec (needed for msrle)

* modules/codec/ffmpeg/video.c: fixed crash when disabling post-processing with videos with B frames.

* include/vlc_common.h, include/vlc_es.h: new video_palette_t structure.
* modules/codec/ffmpeg/*: support for palettized codecs.

* ffmpeg.c: 0.4.8 ifdef'ing

* modules/codec/ffmpeg/video.c: setup dummy palette to avoid segfaults with some codecs.
* modules/codec/ffmpeg/ffmpeg.c: more fourccs.

* configure.ac: detect if libavformat is present.
* modules/codec/ffmpeg/demux.c: new experimental demuxer using libavformat (most of the work done by fenrir).
   This demuxer should allow us to support "frindge" formats (FLIC, SWF, etc...).
   The demuxer has been put here because of its dependancy on libavformat and libavcodec.
* modules/codec/ffmpeg/ffmpeg.c: re-arranged the codecs list.

* modules/codec/ffmpeg/video.c: respect aspect ratio given by demux if any.

        - open the codec after that p_context has been fully initialisated.
        (fix ASV1)

* src/input/input_dec.c, include/vlc_codec.h: added 2 callbacks in the decoder_t structure for pictures linking/unlinking.
* modules/codec/libmpeg2.c: restored pictures linking/unlinking code.
* modules/codec/ffmpeg/video.c: idem and reenabled direct rendering even when the hurry-up mode is activated as it doesn't seem to create a problem anymore with recent ffmpeg.

* modules/gui/wxwindows/*: added new codecs for stream output.
   Added ffmpeg postproc to menus.
* modules/codec/ffmpeg/*: allow switching postproc filters on the fly.

* modules/demux/*: some containers don't carry any PTS information, just a DTS. In that case, make sure the PTS forwarded to the decoder is set to 0.
* modules/codec/ffmpeg/video.c: use PTS if available, if not find out the PTS from the DTS and the p_context->has_b_frames and p_pic->reference flags.

 as vlc/vlc.h include them).

* src/misc/modules.c: win32 fix for when module fails loading.
