* 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.

 are not!

-replaced dvdcss_title(,) with dvdcss_seek( ,,DVDCSS_SEEK_KEY )

*Updated local libdvdread, so that it does not depend on libdvdcss
(ala dummy_dvdcss) and modified configure to reflect changes.

* mad PTS should finally be accurate
* Some configure changes.

+ libmad_input now takes one frame at a time (see mad_adec.h for defines)
+ audio_linear_dither() gives better sound quality then s24_to_s16_pcm(),
  but also makes audio artefacts louder so disabled it for now (see file
  mad_libmad.c)
+ cleaned up libmad_output (see file mad_libmad.c)
+ cleaned up InitThread (see file mad_adec.c)
+ Made buffer size match libmad's expectations (see file mad_adec.h)
+ updated documentation

* Fixed crashes on exit in the directx plugin
* vout_PlacePicture is now accepting picture width=height=0

* Win32 (NT/2000/XP) fix for libdvdcss: first attempt to open the DVD
  device in read/write mode so we can use ioctls. If this fails
  (insufficent privileges) we at least open in read-only mode so the
  libdvdcss title decryption method can be used.

  * ./configure.in: added extra checks for strange compilers such as
    Borland C++ which do not support all gcc options. Note that vlc does
    not compile with bcc32 yet, but is getting closer and closer to.

  * ./plugins/win32: skeleton for the win32 interface Ipkiss is developing.
  * ./config.guess ./config.sub: latest GNU versions.
  * ./configure.in: when possible, xvideo is compiled as a plugin.
  * ./vlc.spec: fixed a few minor inaccuracies.
  * ./debian/control: vlc-gui is no longer depended on, but rather recommended.
  * ./src/interface/main.c: --spumargin flag; use this to force displaying
    subtitles at the bottom of the screen instead of putting them in the
    middle, for instance: `--spumargin 5'.

* Converted the plugin initialization code of the macosx, beos and qnx
    code. (please note that they should still not compile as they need
    to be adapted to the new Vout4 architecture)

* major rewrite of the directx video plugin to adapt it to the new vout4
    architecture. This plugin has also been through a major clean-up
    and it is now much more robust and optimized.

* Fixed a few problems with the win32 build.

* Replaced the "overlay" command line option with "nooverlay". The
    former was confusing and useless because overlays were used by
    default anyway.

  * ./vlc.spec: imported MandrakeSoft's new spec file.
  * ./debian/control: fixed build-dependencies for vlc-mad.

  * ./debian/rules: fixed the vlc-arts and vlc-mad package builds.

The gnome/gtk interface should no longer user p_input->stream before it
has been initialized.

to have it initialized when we call it in the interface.

- added support for S8 and U16 aout (not tested)
- The sound is very dirty in U8 mode. I don't know if it comes from the
8 bit mode itself or from the S16->U8 conversion.

-Patch of libdvdread to do readv on regular files (dvd copied on hard drive).
Not completed, and little tested yet ; when it is completed, this patch should
be submitted to libdvdread developers.

-Patch of libdvdcss to decrypt vobs when they are not on a block device.

  * ./debian/control: fixed Debian build-depends.
  * ./include/config.h: changed RELEASE to HAVE_RELEASE because RELEASE
    is already defined in <scsi/scsi.h> under Linux.

* Fixed issues in the PTS handling of the mad plug-in (incomplete).

*With DVDCSS_METHOD=disc or key, the keys are no longer buffered on start.
The title key is still read at each block but it is checked for change
before decryption.

- le coup de gr�ce: all the code in audio output is now factorized (except
for ac3 spdif) in aout_common.c/.h
- aout thread functions are declared with a macro

TODO:
- test unsigned 8 bit output, and implement S8 and U16 outputs
- multi-channel support
- check if resampling takes the PTS into account (and fix it)

HUGE cleanings in audio output:
- removed AOUT_INTF_*_FIFO, which where not used
- factorized S16StereoPlay, U8MonoPlay, and so on.., in a single
  function aout_FillBuffer (in aout_common.c)
  (unsigned 8bit may be broken, but I have no stream to test with :(

- last step to be done: factorize aout_s8, aout_s16, ... thanks to a macro
