* include/codecs.h:
  - created a subtitle_data_t to be used by subtitle demuxers
    and decoders to pass information.
  - ToDo: access/dvd/es.c and spudec need to be fixed to use the palette field
    of this new struct.
* modules/codec/subsdec.c:
  - moved the decoding of ssa textlines to here.
  - ToDo: support for any tags is lacking atm., but now possible.
* modules/demux/mkv.cpp:
  - ssa is now passed undecoded to ssa subsdec.
  - ssa headers are passed to ssa subsdec via subtitle_data_t
  - ToDo: decode idx header info and fill the subtitle_data_t
  - ToDo: support for compressed vobsubs.
* modules/demux/util/sub.?:
  - moved ssa decoding out of here.
  - ToDo: add support for multiple tracks
  - ToDo: implement reading vobsub .sub files (not .idx)

  we can now read the .idx file. TODO:
  - create a structure to store subinfo in (like WAVEFORMATEX and BITMAPINFO
  - allow for multiple tracks in the sub demux
  - open the .sub vobsub file, remove the mpeg crud and prepare a packet
    for spudec.

* ALL:
  use a counter and pass this along to New_Subtitle, so we can add more
  than one subtitle file. This 'fixes' a problem where all subtitles got the
  same track_id and therefore were all (un)selected at the same time.

  make it easier for users to find their charset now.
* modules/demux/util/sub.?: try to find filename.subext based on filename.avi
  Very basic now, but might be become more advanced in the feature. (that's
  why it's so much code )

* modules/gui/wxwindows/*: you can now specify input options in the stream output MRL as well.
* modules/misc/freetype.c: bail out if no font has been specified.
* modules/demux/util/sub.h: don't forget to detach the demuxsub object.

* modules/misc/freetype.c, modules/demux/util/sub.c: cleanup.
* modules/demux/util/sub.h: thou shall do a vlc_object_attach().
* src/misc/variables.c: added VLC_VAR_FILE and VLC_VAR_DIRECTORY inheritance support.

libavcodec). This fix mpeg4 in TS with huge bitrate.
 * sub: clean up. Report any problems.

MicroDVD, SubRIP, SSA subtitle format should work...
 Options: --sub-file <subtitle file> [--sub-fps, --sub-delay --sub-format].

 * modules/demux/avi : make use of subtitle parser.
 * modules/demux/asf : display movie length. (It will not work with live
streams of course).

 modules/codec/spudec : use i_dts to send end of display time for subtitle.
(Yes it's ugly, but it works :)
