(when the last vout is closed, the interface reappears)
       Works only with the skins interface and X11/Xvideo vouts, but it's
       very easy to implement (just add a callback on "intf-show" in the
       interface, and trigger it in the vout)

* modules/audio_output/alsa.c: the aout-device obj var wasn't destroyed properly on probe() failure, preventing other audio plugins from working afterwards.
* modules/gui/skins/src/skin_main.cpp: got rid of the skins shortcut.
* modules/gui/wxwindows/*: the popupmenu is not created inside the timer anymore so the slider will still be active when the popup is triggered.
* modules/video_output/directx/events.c, modules/video_output/x11/xcommon.c, src/playlist/playlist.c: new intf-popupmenu obj var to handle popup context menu requests from the vouts.

* configure.ac.in, modules/video_output/x11/xcommon.c: fixed configure check for the Xinerama extension.

* modules/video_output/x11/*, configure.ac.in: Xinerama support remotely based from an old patch by Xavier Maillard.

* src/video_output/video_output.c, modules/video_output/directx/*, modules/video_output/x11/xcommon.c: fullscreen state is now attached to the input, so it will be remembered even if the vout is restarted (switching filters, dvd menus, etc...).
* modules/video_filter/deinterlace/deinterlace.c: small change.

* ALL: removed the old channels server stuff (was deprecated).

fullscreen and a nice debug message when you draw a clockwise square. Video
output modules needs to be modified for this to work, but it should be minor
in modules supporting dvd navigation.

btw: it should be easy to add new gestures, ideas appreciated

  * ./modules/video_output/directx/directx.c, ./modules/video_output/x11/x11.c,
    ./modules/video_output/x11/xvideo.c: removed the drawable configuration
    variables which are now deprecated.

* modules/video_filter/deinterlace/deinterlace.c,
  modules/video_output/x11/xcommon.c: modified debug messages.

    events once our window has been properly mapped.

  * ALL: a bunch of additional warning fixes.

and is replaced by two members : i_physical_channels and i_original_channels.
i_physical_channels describes the channels which are effectively present
in the stream (at the current point of the aout pipeline), whereas
i_original_channels represents the channels we used to constitute the
stream. For instance a mono stream (FRONT_CENTER) may emanate from a
FRONT_LEFT channel of a STEREO stream.

Additionally, this contains hooks to dynamically select the audio device
and the channels configuration. In order to do that, all aout plugins,
and all interface plug-ins need to be adapted. Currently only SDL
(partially OSS) and the rc interface have been adapted, please use them
as a guide. Other aout plug-ins have been temporarily disabled.

IMPORTANT : if you need a working sound output, DO NOT UPDATE YOUR TREE
for several days until we fix that.

* modules/misc/network/ipv4.c: Fixed a long-standing segfault when saving
  preferences and asking for multicast.

  * ./modules/video_output/x11/xcommon.c: we transmit the click only at
    release time.

  * ./modules/access/dvdplay/intf.c: instead of probing the mouse on each
    loop iteration, we set a callback on the corresponding variables.

    in the Mozilla plugin, we do not try to unmap it.

* modules/video_output/x11/xcommon.c: fixed a bug related to the size of the
fullscreen window. We also unmap the current window when switching to fullscreen.

    (compilation fix for Solaris).

    waveout, directx, qnx, beos, win32, macosx, and the AltiVec modules.
  * ALL: removed mention of AC3 in favour of A52.
  * ./configure.in, ./Makefile*: modules can now be built deeper than 1
    directory. As a consequence, the build is even slower (but I'm fixing
    this) and make clean doesn't work anymore.

    about 2000 lines of code.

    I could not test everything on every architecture, so please report
    any module breakage (especially on BeOS, OSX and QNX).

  * include/input_ext-intf.h: killed p_es->b_audio, since i_cat already fills
    its purpose.
  * include/input_ext-intf.h: killed p_es->i_type in favour of p_es->i_fourcc.
  * include/video.h: killed p_pic->p_plane->b_margin; now i_visible_pitch is
    always valid.

  * ./src/libvlc.h: replaced --mpeg-adec and --ac3-adec with --codec; see
    vlc --help for more information.

  * include/video.h: removed fourcc values which should _not_ be global
    (thanks fenrir for convincing me).
  * ALL: video output plugins use the VLC_FOURCC macro to build their fourccs.
  * ./plugins/beos/InterfaceWindow.cpp: removed the last remaining call to
    input_ChangeES.

   Things I'm not sure about and need comments:
    - I used "mpga" and "mpgv" for MPEG (1+2) audio and video fourcc values.
    - I also introduced "spu ", "lpcm" and "ac3 ".
    - I removed for instance "MP4_GetCodec" because it wasn't really
      used except for the description string. I hope this change did not
      break anything really important.
    - fenrir, I must have broken a lot of things you wrote. Sorry in advance.

  * ./src/libvlc.c, ./include/vlc/vlc.h: created reentrant versions of the
    libvlc API.
  * ./src/vlc.c: vlc uses the non-reentrant libvlc functions.
  * ./mozilla/vlcplugin.c: the mozilla plugin uses the reentrant functions.
  * ./debian/*: created packages for libvlc0-dev.

    instead of moving the current window, which saves us the hassle of
    remembering size and position.
  * ./plugins/x11/x11.c, ./plugins/x11/xvideo.c: added --no-x11-shm and
    --no-xvideo-shm options.

    tell vlc to draw in an existing drawable instead of creating a new window.

and they are used nowhere.

  * ./src/interface/interface.c: interfaces are no longer attached only to
    p_vlc.
  * ./src/libvlc.c, ./src/misc/modules.c, ./src/playlist/playlist.c,
    ./src/input/input.c: improvements in the playlist handling (not quite that
    yet though).
(ported from v0_4_1_branch)
  * ./configure.in, ./plugins/mpeg_system/mpeg_ts.c: fixed libdvbpsi handling.
  * ./src/misc/configuration.c: fixed the --nofoo option handling.
  * ./src/interface/main.c: fixed two compilation warnings under Solaris.

    bug which might have been the cause of crashes.
  * ./plugins/filter/crop.c: attempt at an automatic border cropping filter,
    using "--filter crop --autocrop".
  * ./vlc.spec: added missing filters to the RPM generation.
  * ./src/misc/objects.c: commented all functions.
  * ./src/misc/objects.c: implemented vlc_object_find( , , FIND_ANYWHERE).
  * ./src/misc/objects.c: renamed vlc_object_unlink to vlc_object_detach.

   As for video output 4, this breaks almost everything, but I'll slowly
  do what remains to be fixed during the weekend.

   Changes in vlc:
   ===============

  * vlc is now a very small program (20 lines) which uses the libvlc API;
   it is quite simple for the moment but can be extended in the future.

  * interfaces, decoders, video outputs, etc. are now almost the same
   objects (yes, I know, this is C++ redone in C) and are structured in
   a tree. More about this later, but basically it allows the following
   nice features:
    - several interfaces
    - several playlists with several outputs
    - input plugins spawning helper interfaces (will be used for DVD menus)
    - anything spawning anything; I swear there are useful uses for this!

  * libvlc can be used in other programs; I'm currently writing a Mozilla
   plugin for my employer.

   Things currently broken:
   ========================

  * most interfaces, most ports
  * the playlist handling (almost finished rewriting this though). This means
   no file can be played from the GUI, you need to use the commandline. This
   also means it segfaults at EOF, when exiting the program, and it sometimes
   refuses to open a file when asked to.

* ./plugins/dummy/dummy.c: added a CATEGORY_HINT to the config.
* ./plugins/x11/xcommon.c: small change to the ToggleFullscreen routine
to avoid a flickering during the switch.

    on t'aiiiiiiiiimeuh).

    and mipspro doesn't know about __inline__).

    force the XVimage format used.

* video plugins that don't handle rescaling themselves have to let the
  video_output thread know about resizing events (with VOUT_SIZE_CHANGE event).
  (this part needs some clean-up but it is basically working for the X11 and
   SDL plugins).

* fixed fullscreen for the SDL plugin.

* xmga and sdl now switch to fullscreen on double-click.

* fixed the resizing and scaling of the X11 video output.
* clicking on the video doesn't pause it anymore (use spacebar for this), but
  double-clicking will now switch between fullscreen and window mode.

    mode, the Esc key does not quit immediately, but first escapes from
    fullscreen mode. User-requested feature.

  * ALL: removed underscores from option names and made a few options more
    self-explanatory, for instance --input_channel becomes --audio-channel;
    run vlc -H to see what has changed.
  * ALL: replaced many occurences of "plugin" with the word "module".
  * ./src/interface/main.c: moved all satellite-specific configuration options
    to the satellite plugin.
  * ./po/*: updated translations.
