fr.po: minor fixes

  - don't crash when i_output < 0

   A few users have been reporting problems with the directx audio output and it might very well be the cause of their problems (ie. with buggy drivers).

  - Fix Playlist Save. Can only do m3u atm.

  --macosx-stretch mode. Ignore aspect ratio and stretch video to fill window.

* modules/gui/wxwindows/wxwindows.cpp: include setlocale.h after the vlc headers.
* modules/gui/wxwindows/menus.cpp: fixed memory leaks.
* modules/gui/wxwindows/playlist.cpp: fixed deadlock.

* modules/gui/wxwindows/playlist.cpp: removed useless lock.

* modules/gui/wxwindows/*: a whole bunch of bug-fixes spotted by running the debug build of wxWindows.

Removed unused files.

This file need reviewing, please help

* src/input/input_dec.c: compilation fix.

* modules/packetizer/mpeg4audio.c, modules/packetizer/mpegvideo.c: compilation fix.

* modules/gui/wxwindows/menus.cpp: try to display choices menus in a more clever way (hide useless things like empty menus).

* modules/demux/dts.c: improved detection of wav dts files.

Strangely, the "AddPendingEvent" wxwindows call seems to hang, so
replace it bhy "ProcessEvent" (the playlist update is processed
immediately in the callback, but it is only the update of one item, so
it should not be a problem)

* modules/access/cdda.c: added "cddasimple" shortcut.

* modules/stream_out/transcode.c: compilation fixes for ffmpeg-0.4.8.

* modules/demux/wav.c: more fixes for multichannel wav files support.
* include/codecs.h: ms speakers definitions.
* modules/codec/araw.c: added support for fl64 fourcc.

* src/playlist/playlist.c: who said testing was useful ?

* src/playlist/playlist.c: bug fix.

 * fixed two memleaks, one of them rather large
 * fix for http announces that don't start the filename part with '/'

 using weird value after a synch with RTCP.

* include/vlc_common.h: added the UI64C() macro for unsinged long long constants.
