* 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.

  work now.

 is buggy).

this required new libvcdinfo API - so change to configure.ac for
pending new libcdio/vcdimager releases.

Additional libvcdinfo routines also means less VCD twidling inside vlc
code, thus simplifying what is already a bit complicated and likely to
get more so.

    -> but untested under OS X and win32.

    - also check for p_dec->b_die and b_error.
    - unload module before joining thread (in DecoderThread) otherwise qt
    win32 dll loader will segfault. (but perhaps I'm the only one using it)
        -> find a better solution.

 as vlc/vlc.h include them).

  -> i_rate isn't used for now : it will need to be fixed.

* configure.ac: get rid of the oggpackB_read check in libogg because we don't use it anymore.

* include/input_ext-intf.h, include/vlc_es.h: moved ES categories into vlc_es.h
* modules/codec/lpcm.c: ported to the new decoders api + lpcm packetizer.

 (may be readded later).

 * mpgv.c: new demuxer using the packetizer (allow to stream ES).

    + Fixed internal symbols for version numbers containing "+".
    + Added a --enable-caca flag.
  * modules/video_output/caca.c:
    + Updated libcaca video output to the released version.
    + Added --caca-dithering flag (none, dither, random).

* modules/codec/tarkin.c: ported to the new decoders api (I know, this is a waste of time ;).

* modules/stream_out/transcode.c: put back the dumb downmixing routine.

* src/input/input.c: fixed previous fix (sout needs to be destroyed after the ES).

* src/input/input.c: don't free the ES twice.
* modules/demux/ogg.c: ported to the es_out_*() api and fixed flac support.
* modules/codec/flac.c: couple of fixes.

 * fixed a minor memory leak

 * fixed a possible buffer overflow

 * fixed a couple of nasty memleaks

   interface because this makes crash others interfaces which might be
   still using it (e.g. sap)

 + *threads*, src/libvlc.h:
   test HAVE_KERNEL_SCHEDULER_H before PTHREAD_COND_T_IN_PTHREAD_H
   for now because Zeta now has a pthread implementation but it's doesn't
   seem to be (enough) POSIX compliant atm.

* modules/codec/flac.c: added a FLAC encoder.
* modules/mux/dummy.c, modules/mux/ogg.c: you can output "normal" flac streams with the es/dummy muxer or output them with an Ogg container.

* modules/gui/wxwindows/*: drag&drop on the playlist only enqueue.
   Small cosmetic change to the playlist.
