structures of DVDs
-Change in configure to avoid compiling css functions on BSD.

 . added comments to src/interface/intf_plst.c and include/intf_plst.h
   so that people understand how the playlist works.
 . updated the TODO list (34 items to do, 41 done !)

  GNU/Linux options ;
* Changed fseek() to fseeko() for 64-bit offsets ;
* Reset frame predictors on a stream discontinuity.

  and jump Backward in the SDL intf. Enjoy !

Maybe it would be a good idea to compile the DVD plugin on machines which
have one ? :pppp

 . moved the playlist handling from input/input.c to interface/interface.c
 . fixed a few warnings at compile-time
 . fixed sound channel selection in playlist mode
 . added a color message in the plugin bank because on peut bien d�conner
   cinq minutes, quand-m�me
 . we now spawn a new input thread for each file
 . added a missing pf_close() because it's always cool to close files
   after we read them

plugins. I will fix that soon.
-minor modification in pluginification.

   This commit is a bit early, but it'll save Stef, Henri and me much
 time later, when we don't have to backport modifications to input_*.c

   What's new :
    - playlist works again (still the old wrong way like Meuuh doesn't
    like, but this is going to change within a few hours)
    - input_ps, input_ts and input_dvd are now plugins, located in
    plugins/mpeg/ and plugins/dvd/

   What's broken :
    - audio output might be broken on some streams ; have to investigate

   What has changed :
    - fast/slow keys are now A/Z instead of A/S since S was already
    linked to the scale/noscale toggle.
    - `--dvd' doesn't work anymore, for the moment try to use :
     vlc --input dvd /dev/dvd
    - module bank is now less verbose ; use `--warn 1' to turn back
    verbosity on

2048 bytes.
-Some modifications in netlist to make it work with DVD.
-Fixed � bug in mpeg_system.c

We use INPUT_READ_ONCE many times in the input code. I think that
we should replace it with a field in input_thread_t to give more
flexibility to modules. I have done it in DVD plugin but it can't work
if input.c is limited by INPUT_READ_ONCE.

The DVD method is slower than input_ps ; but there are things to
improve.
CSS descrambling is broken.

Thanks to Meuuh, he's MORTEL ;)

* Dirty hack in the SDL intf to bind "a" (fAst forward), "s" (Slow motion)
and "p" (Play).

* Fixed a bug in the management of the first video PTS.

. Used instead p_vout->i_changes like in x11

 . patched 2 debian bugs
    (see http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=vlc)
 . improved the snapshot generation

. Default is shown.
. Default in fullscreen is hidden.

 . removed obsolete video_yuv_mmx.S
 . updated the TODO list and wrote a small todo.pl parser to make it
   easier to see which items remain to be done
 . `make snapshot' now creates vlc-*.tar.gz and vlc-*-nocss.tar.gz

 . version 0.2.50 for the Linux Expo
 . --overlay and --fulscreen options (only work with --vout sdl)
 . the vlc exits after the end of the stream, which prevents from having
   to kill it and relaunch it during a presentation, just script it like :

      for i in ~/mpeg/* ; do vlc --fullscreen --overlay --vout sdl $i ; done


 Yes, I know the --overlay stuff is fucking ugly. But *I* am not the one
  who redefines vout_sys_t in an interface-related source file. I won't
  change it until the vout/intf is finished being rewritten.

 Additional information: if "--overlay --fulscreen" doesn't center your
  picture, try with your screen geometry, eg:
  "--overlay --fullscreen --width 1024 --height 768"

  no -a option is specified, the vlc will play the first audio type it finds,
  so there is no need to specify "-a ac3" for a DVD anymore.

It is very slow now but will be more adapted to the forthcoming DVD
input.
It should read the first title of many DVDs but has been tested with few.

-Beginning of ifo commands to implement DVD navigation.

 . removed Makefile -- I can't understand why it reappeared.

* Updated TODO list.

I have only tested it on my computer ; so I don't know if it work
elsewhere, particularly on BSD and BeOS.

Now it generates a valid title key, but there is no sector descrambler
yet.
