Compilation fix.

    it, no need to manually add it.

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

try to detect end of file.

* moved the function definitions from threads.h into threads_funcs.h. This
   allows us to move p_main_sys into p_main (p_main->p_sys).
* fixed the --with-gtk-config-path and --with-sdl-config-path options in
   configure.in

* updated win32 compilation instructions.

    * plugins/avi/avi.c : now it can play broken file with seek enable but it's very slow (will be fixed soon ).

    * src/input/input_programs.c : an video divx ES will no longer be considered as an audio ES ( thanks sam ).

- New creator ID : VLC#
- Borders in fullscreen mode are now black and the movie is centered
  (jlj P0\/\/3r)
- A/V sync should be much more precise

  * ./include/video.h: moved vout_CopyPicture out of the way, an inline
    function did not make sense here.
  * ./include/video.h: moved vout_ChromaCmp out of the way.
  * ./plugins/avi/fourcc.h, ./include/video.h: merged these two files into
    video.h.
  * ./include/os_specific.h: this file is now always included.
  * ./include/debug.h: removed this file which was almost useless, and moved
    ASSERT to common.h.
  * ./include/common.h: fixed vlc_memalign and changed its prototype to
    follow posix_memalign's.

    safer variants $with_foo and $enable_foo.

    * plugins/avi/avi.c : use KeyFrame to seek, so video will not be bad as
        before

* Added a mpeg_ts_dvbpsi module tha uses libdvbpsi to decode PSIs. It is
  used by default if the lib is found. It shares much code with mpeg_ts

* fixed typo. You have to double click on the video window to switch to
  fullscreen.

* on Win32 the config file is now stored under the "Application Data" folder
  belonging to the user. (this works if at least IE4 is installed, otherwise
  the old method is used to get the config directory)

  * ALL: renamed PLUGINS to __PLUGINS__ to avoid conflicts with libraries
    defining it. Grmbl.
  * ./src/input/input_ext-plugins.c: cosmetic change.

* ./plugins/avi a light  avi demux
* ./plugins/ffmpeg a video decoder for divx v3 and opendivx

 * plugins/win32/preferences.cpp: fixed a compilation bug

    upcoming work.

* DirectX video output plugin now uses triple buffering for YUV overlay. This
  improves the video quality a lot (no tearing) without affecting performance.
  (I knew double buffering sucked but I just discovered why triple buffering
   is better: you don't have to wait for the vsync to flip the buffers).

* Fixed the DirectX video output for non-overlay modes. It was only working
  in RGB16 before.

* Fixed the mouse autohidding feature in the DirectX plugin
 (at least partially).

* Fixed the spu decoder to take the pitch of the destination picture into
  account when rendering the subtitles (Implemented only for the YUV modes).

    to avoid retrieving the spu palette from a network stream as if it was
    a DVD.

  * 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.

    transformations. They're now PIC-friendly as well.
