in multi-program streams (such as ones provided by a DVB-S card).

This is the first part of the new configuration architecture for vlc.
Two other parts will follow soon:
- config file implementation
- gtk configuration interface.

This part won't change much for end-users as these changes are mostly
internal, you will however notice that the command line interface has
changed. It will maybe be less user-friendly as I almost removed the
short options but it shouldn't a big problem when the config file is
implemented.

What as changed is that it is really easy now to add configuration
options to vlc. Plugins can also implement configuration options. All
you have to do is to declare a MODULE_CONFIG section in your plugin.
If you want to know more about this look at configuration.h and for some
example: main.c, dsp.c or xvideo.c

It would be nice if every developper could now start using configuration
options in there plugins and also enhance old plugins.

That's it, now let's hope I didn't break too many things ;-)

* fixed array over-run bug in intf_MsgUnsub

* Don't try to grok altivec with mingw32.
* --with-directx-path should now indicate the path where the actual
headers are (before the headers had to be in an include subdir). By the
way you can download these header files from the videolan web site.

  * ./src/misc/modules_plugin.h: if symbol foo isn't found in the
    plugin, we always try to open _foo, whatever the architecture.

  * ./plugins/lirc/lirc.c: non-blocking patch from Sigmund Augdal
    <sigmunau@stud.ntnu.no>; hope this time my enhancements don't break
    everything :-)

  * ./configure.in: gtk*-config detection fix for FreeBSD.

  * ./configure.in: removed a bashism.
  * ./plugins/x11/xcommon.c: support for systems without shm.h.
  * QNX compilation fixes here and there; the qnx plugin still doesn't work.

  * ./Makefile: the win32 port now uses a more recent version of gtk+.

  * ./plugins/gtk/gtk.c: the log window is now black with colourful text.
  * ./plugins/gtk/gnome.c: ported the log window to the GNOME interface.
  * ./src/interface/intf_msg.c: messages are sent to the queue even if
    -vvvv* wasn't specified.

  * ./plugins/lirc/lirc.c: fixed my mistakes from yesterday.

  * ./plugins/lirc/lirc.: various fixes, thanks to Sigmund Augdal.
  * ./plugins/text/logger.c: rewrote an ugly loop.
  * ./plugins/gtk/gtk.c: added a Gtk+ window containing all the log
    messages; updated in real time. To open it, go to "view"->"messages".

   * Got rid of TRACE and intf_DbgMsg which were seldom used anyway.
   * All intf_*Msg functions now write to stderr.
   * Implemented a message queue interface plugins can subscribe to.
   * Wrote the logger interface plugin. Usage:
      vlc -I logger:filename.log
   * Lots of fixes in the SPU renderer.

  * MacOS X intf now returns, allowing vlc to terminate properly
  * Added a new make target: package-macosx

* Win32 compilation fixes (mingw includes dirent)
* configure now checks for ddraw.h and not directx.h
* vout_directx doesn't include directx.h anymore (this file isn't part of
    the directx sdk)
* moved all the stuff from aout_waveout.c directly into waveout.c (I don't
    know what I was thinking about when I created these two files ;-)
* until we fix the audio buffer underrun problem, waveout will be the
    default audio output on win32 (instead of directx).

  * ALL: got rid of *_Probe functions because most of them were duplicates
    of the real _Init or _Create functions. That's 1000 lines of code gained.
  * ./src/misc/modules.c: we try not to keep the global lock in module_Need,
    which should speed up output spawning.
  * ./plugins/dummy/input_dummy.c: fixed vlc:quit command.
  * ./plugins/gtk/gtk_playlist.c: compilation fix.
  * ./plugins/macosx/*: preliminary fixes for the vout4 port.

   Notes on the *_Probe eradication:
  o I probably broke the DirectX video output, because of the "must init and
    run in the same thread" issue. I'll fix this ASAP.
  o Subtitles are broken (or at least, pretty ugly) in RGB mode.
  o The input plugins still have *_Probe functions. This will disappear when
    meuuh is finished with the access plugins.
  o The decoder plugins still have *_Probe functions. This is probably not
    going to change, it looks OK to me.

  * Grmbl. Forgot to commit those Win32 fixes last time, and they were
    stuck on VTHR. Sorry xav, this probably explains why I couldn't
    find the commit log :-)

  * ./plugins/beos/*: BeOS fixes from Rudolf Cornelissen.
  * ./src/interface/main.c: --desync now really accepts a value in ms.
  * ./plugins/vcd/input_vcd.c: fixed a crash when not opening a VCD.
  * ./src/video_output/vout_subpictures.c: fixed subtitles under BeOS and
    other architectures which don't support overlay.

* compilation fix (include stdint.h)
* fixed a SEGV

  * ./plugins/beos/vout_beos.cpp: ported the BeOS RGB video output to
    vout4. The overlay video output still needs to be written though.

* Just renamed the liba52_adec plugin into a52 to comply with the naming
convention used by the other plugins.

    <sigmunau@stud.ntnu.no>, activate with --enable-lirc.
  * ./configure.in: put liba52_adec in a builtin for PIC/non-PIC reasons.

* New AC3 decoder plugin using liba52 from Aaron Holtzman and
    Michel Lespinasse.
    This plugin isn't used by default, you have to specify:
    --ac3_adec liba52

  * ./src/misc/modules.c: changed module_Need to make it possible to
    have several modules with the same shortcut name.

  * Fixed stuff in the wall filter. Extended syntax:
     --filter wall         % open a wall (3x3 is the default value)
     --filter wall:2       % open a 2x2 wall
     --filter wall:3x2     % open a 3x2 wall
     --filter wall:2x1:0   % open a 2x1 wall, only display block 0
     --filter wall:2:0,3   % open a 2x2 wall, only display blocks 0 and 3
    For instance, if you have 2 computers listening to a network stream, on
    the left computer you use --filter wall:2x1:0 and on the right computer
    you use --filter wall:2x1:1

* Added mstrtime() to module_symbols_t so we can compile the mpeg_vdec
    plugin with TRACE mode enabled.

-Check frequency in ac3_adec and change fifo if needed,

-Moved initialisation of p_aout from plugins to audio_output.c
If audio output rate is psecified at launch time, we try to use it by default.

Note that audio output currently suffers from frequent underruns.
This has not been fixed here.

* Added double-buffering for the directx plugin in overlay mode.
* Several directx bug-fixes:
    - implemented the right behaviour on exit.
    - fixed bug preventing the creation of several windows.
        (the wall filter is working now :-))
    - fixed unnecessary background redraws (it made the video flicker).
    - fixed bug where we were losing the video display because of lost
        surfaces in video memory.
    - when using hardware overlay, the output window will now specify:
        "(using hardware overlay)".

  * ./plugins/x11/xcommon.c: we don't use DPMS functions if they are
    not available.

* Added a new very simple audio plugin for Win32. This plugin uses the
    waveOut API which is a lot easier to use for streaming stuff than
    directsound. (you don't have to take care of underflows anymore
    because it doesn't use circular buffers).
    If you are having a lot of underflows, this plugin is currently
    better adapted than the directx plugin.

* Moved some initialization stuff in audio_out.c so we can now the
    caracteristics of the audio stream before calling aout_Open().

It is now activated with option --with-dvdread, that takes the same options
as --with-dvdcss.
If you link with libdvdread statically dvdread is compiled builtin ; if you
link dynamically, it is compiled as a plugin.

  * ./src/misc/modules_plugin.h: fixed a missing function initialization
    which made decoder plugins segfault in GetChunk calls.
  * ./configure.in: proper soundcard.h check from Yves Duret.
