(thanks Garf)

* modules/codec/mad/*: don't let mad drop corrupted mpeg frames without telling us. When
this happens, we miscalculate the pts of the next valid frame, which in turn causes heavy
resampling. This fix should be most useful for web radios.

The following things have still to be fixed:
- segmentation fault on destroy
- video placing and
- orientation
- video line spacing is wrong

p_input->stream.p_selected_area->i_tell when reading data. (It's done in
input_SplitBuffer). (But access should still set it on a "seek")

* modules/demux/wav/wav.c: small bug-fix for screwed pts calculation.

* src/audio_output/filters.c: fix for resampler buffer size.

* ALL: fixed a f*ckage I introduced recently ;) var_Type() now returns 0 when the variable
doesn't exist, but the rest of the code wasn't updated according to this new behaviour.
* modules/audio_output/waveout.c: changed a few error messages into warning messages.

* include/configuration.h: fixed my previous fix.

* include/configuration.h, include/modules_inner.h: proper fix for a bug that allowed gcc
to put things in the stack instead of the data segment.

one (Please reports if it doesn't).

* include/configuration.h: rolled back the last changes made to this file. There is no
sense in manually initializing all the fields of module_config_t as it will be done by the
compiler anyway. Furthermore mingw32 gcc seems to have problems optimizing code
that manually initializes structures to 0.

 * VlcWrapper.h, Interface.cpp: removed an unused variable.

    audio output;
 * VlcWrapper.cpp: handle volume using aout3 features.

  --disable-dvd works anyway.

  effect should give you the feeling that you stands in a real room with
  a complete 5.1 speaker set when using only a headphone, providing a
  more realistic sound experience. It should also be more comfortable
  and less tiring when listening to music for long periods of time.It
  works with any source format from mono to 5.1.

  -> please try it and feel free to give me some feedback. Some
     improvements are already planned (adding echo, more configuration
     options, ...).

NB: whereas the filter itself is in a (very first) stable version, the
    way it is integrated to the filter chain is only a _temporary_ hack
    since it's the audio ouput core (input.c actually) which is directly
    responsible for it. Integrating it in a more suitable way will
    probably require some work on the way the filters are selected as
    well as on the configuration level, but I'm working on it :)

* Reworked the Open... menu items, and added the ability to use libdvdplay.
* Sound output menu is now under Controls.

* modules/gui/wxwindows/*: compilation fixes for wxX11 (it doesn't support drag and drop
yet). Compilation fix for MacOSX as well (wxEntry() not declared).
* src/misc/variables.c: added a FreeMutex() function.

- fixed --disable-dvd, it did not work
- updated iPaq familiar buildscripts

* configure.ac.in: fix for dvdread and libdvdplay plugins linking stage.

         intf. wxWindows should work (not tested). Closes #33.

thread.

  warnings than real ones.
* audio output: New intf-change variable to know when audio-channels
  and audio-device have changed.
* video output: New intf-change variable and vout_VarCallback, to know
  when video-device has changed (OS X port).
* modules/gui/macosx/*: Menus for audio channels, implemented volume
  management, added a menu for screen selection.

   non-overlay mode (thanks Sam).

* ALL: a few updates to the variables API:
  - got rid of the VLC_VAR_COMMAND variable type and introduced the VLC_VAR_ISCOMMAND flag
instead. This simplifies things and avoid the strange command variables behaviour. Command
variables will now trigger their callback on var_Set() like any other variables (look in
modules/control/rc/rc.c for an example).
  - Renamed the VLC_VAR_ISLIST flag into VLC_VAR_HASCHOICE.
  - Added a new VLC_VAR_VOID variable type. This can be useful in conjunction with
VLC_VAR_ISCOMMAND for instance.

* playlist.c : fixed a memory leak
* configure.ac.in : added link flags

* configure.ac.in: fixed typo. For dvdread support we have to check for
 dvdread/dvd_reader.h, not dvdread/dvdread.h.

  * ALL: a bunch of additional warning fixes.

    a bug I found in Read(). No idea whether it was triggered before nor what
    it was doing, though :)

    meant strlen(), removed useless strcmp() calls, implemented atoll() for
    systems where it does not exist, fixed a memory leak, fixed a minor data
    corruption.
