* on win32 the dummy interface plugin will open a dos command box. With
this fix, vlc should never fail silently and leave a ghost process
running in the background when there isn't any working GUI plugin.

* moved the mpeg-motion and mpeg-idct options to the mpeg_vdec plugin
* added a few *_LONGTEXT descriptions to main.c
* on win32 DVD/VCD_DEVICE defaults to to D:

Could anyone finish the *_LONGTEXT descriptions in main.c. There aren't
that many left right now, just the ones I didn't really know what to do
with.
If someone also wants to review and change the already existing
*_LONGTEXT descriptions, he is welcome as well because there are not
really high quality descriptions :(

* Updated documentation.

* updated INSTALL.win32
* a little bit of clean-up in the directx video output plugin

  Bossoreille de Ribou <bozo@via.ecp.fr>

    and mipspro doesn't know about __inline__).

* fixed deadlock in NextFrame() in aout_pcm.c

* fixed a bug in the directx window creation function. We register a window
   class once per process so we must be careful not to free the associated
   resources.

* updated the MSVC++ project files and added support for dirent (vlc compiled
   with msvc can now load plugins - even compiled with mingw).
* small portability fixes.

* Dropped dependancy on autoconf 2.52.

* modified the directx video plugin to try to create an YUV surface before
   falling back to an RGB surface when it's not possible to use overlays.
   Some graphic cards can do the YUV->RGB conversion in hardware during the
   blitting stage.
* in the directx video plugin, we now request that the RGB surface be created
   in video memory. The reasoning behind this is that usually surfaces in
   video memory benefit from more hardware acceleration (like for instance
   hw rescaling, hw blitting, etc...)
* added two options to the directx video plugin to disable the above features.
   (mainly because my video driver is buggy and doesn't handle them well).

* small cosmetic changes to the generation of the config file.

* fix for config_GetHomeDir() on win32. SHGetFolderPath() is located in
   shfolder.dll not shell32.dll.
* fix for the gtk preferences dialog box. To be sure that an int or float value
   is actually changed we call gtk_spin_button_update() in the
   GtkInt/FloatChanged() event handler.

    Debian bug #147103).

 * Fixed my previous commit

 * New Network dialog box for Gtk and Gnome interfaces

waiting for data whereas the vlc has tried to quit.

    calls to realloc(_,0) in a similar way to input_programs.c.

Another fix from Sam:

* fix random segfaults on title change.
  (cell.i_cell_nb should be tested _before_ we access the structures)

* src/input/input_programs.c: fixed memory corruption by setting a few
    pointers to NULL after they have been free()ed.
* src/input/input_programs.c: removed now useless ASSERTs.

This patch comes from sam, so if you want to blame someone blame him ;-)

Lower CPU usage and no thread created per frame.

                     of its own one.

    audio track" problems by zeroing the p_ac3dec structure.
  * ./plugins/ac3_adec/ac3_adec.c: fixed a "INPUT_MAX_ALLOCATION reached"
    crash.

 * plugins/win32/network.*: new Network dialog box
