Added mad plugin downscale config option for selecting downscaling routine. Choices are: fast, mpg321. Default the fast version is used. The downscale option mpg321 uses an algorithm that adapts to dither errors. This routine is borrowed from MPG321 code.
Mono audio streams get now duplicated on the right channel instead of silencing the right channel (untested).

* 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.

* The Apply button in the preferences menu is grayed out unless there's a
  change to apply.
* GtkConfigApply() now clears the list of config changes before returning.

  * ./configure.in: deactivated ipv6.so under QNX for now.

    - no text in the status bar with gtk intf
    - no window title in gtk intf on some machines, correct title on another

    callbacks for the hide tooltips and toolbar text options

The change is needed for MPEG1/2 layer III, because the size of output pcm from mad_decoder is different.
Sadly, the buffer underruns are back ;-(.

    options callbacks.

    They don't take any argument for the moment, but this will change when
    I'm finished with my other vlc changes. There is a little problem: the
    Gtk+ interface keeps calling Put***Variable each time we click on "Apply"
    or "Save". I think it should only call it once. Is there a way to fix
    this? Gildas? lool? :-)

                          After seeking, audio and video synchro is better.

* Fixed VCD double detection

* The configuration file and the log file are opened in text mode. This mode
should only have a meaning on Win32 and isn't supposed to break any other
platform. If does give you any trouble then shout.

* added a --with-a52-tree option to the configure script.

    behaviour with inline assembly (seems to be BeOS-specific). If anyone has
    a better idea than the huge "memory" constraint, please have a look at
    the MMX_CALL() macro!

* added config_Get/PutFloatVariable to p_sysmbols. Thanks to Sigmund Augdal
for pointing this bug out.
* on Win32 the aout_pcm thread is given a high priority. This helps avoiding
lots of audio underruns, especially when moving around the video window.

you can now read your file ;) (but audio is awfull,perhaps because of mad
plugin ? ). Fix a bug for audio with some avi file.

           or libdvbpsi ts demux. Untested cause I can't get our Nova Card
           work again.

* Restored vout_CopyPicture(). It is needed by the directx plugin damnit ;-)
* Restored AOUT_BUFFER_DURATION to its old value. It should solve quite a few
    underrun problems.
* A little bit of DirectX plugin clean-up.

Compilation fix.

    it, no need to manually add it.
