* fix a segfault on close caused by setting default language

* src/audio_output/input.c: on-the-fly visualization changes.
* modules/gui/wxwindows/menus.cpp: added a visualization entry.

  Visualizations menu (is this the right location?)
  Problems currently are: Doesn't work on the fly. where to start?
  For that reason it now also uses config options instead of variables.
* modules/visualization/visual/visual.c: small adaptions
* modules/gui/macosx/controls.m: fix warnings.

  The parsing of lines should of course be moved to the decoder level.

    + Build-depend on a newer wxwindows version to avoid incompatibilities.
    + Build-depend on linux-kernel-headers and build-conflict on dvb-dev
      because these packages cannot be installed together.
  * debian/rules:
    + Temporarily disabled the framebuffer video output plugin because of
       current code errors in linux-kernel-headers.

 transcode).

       PS will work if there is only one stream as the muxer doesn't set
       correctly dts/length for muxed packets. (so pretty useless ;)
        - added mpeg1/2 video. (how overcomplicated is rfc2250),
       tested with mplayer+live.com (but I'm not sure that my ES parsing
       is ok.)
        - btw, there is a ttl option.

       from perfect)
        Use udp raw mode.
        Generate a SDP file (for now it is just fprintf to stderr).
        The streams produced work under gmp4player. (mpeg4ip)

fill packet send to mtu size, needed by rtp)

  we can now read the .idx file. TODO:
  - create a structure to store subinfo in (like WAVEFORMATEX and BITMAPINFO
  - allow for multiple tracks in the sub demux
  - open the .sub vobsub file, remove the mpeg crud and prepare a packet
    for spudec.

* modules/control/hotkeys.c: use demux_Control( p_input, DEMUX_SET_TIME, ...) to seek, for better precision.
* modules/video_output/directx/events.c: fix to catch the Alt key.

 TODO: (a lot of work)
    - gather multiple small frames in one packets (not really important).
    - add mpeg 1/2 video
    - export a sdp file (needed for all next codecs).
    - add mpeg4 audio/video
    - add ts/ps over RTP.
    - perhaps ogg over RTP if something is abled to read that.

 command: #rtp{dst=ip,port=port,[mux=muxer]} (mux not yet implemented)

 It automaticaly uses ip:port, ip:port+2, ip:port+4 ... (port should
 be odd btw)

* modules/gui/macosx/vout.m: removed debug
* modules/gui/macosx/open.m: Panther compilation fixes
* modules/gui/macosx/controls.m: OSDMessages :)

  location by any module.
* added a OSD config option to the Video options. this will allow you to disable
  the messages printed by OSDMessage. Subtitles will still be shown however.
* src/audio_output/intf.c: volumeSet sets the intf-change variable.
* modules/gui/macosx/vout.m: fix the modifier detection.

* include/modules_inner.h: bigger p_config[] array because the main module is becoming quite big.

* modules/gui/skins/win32/*: fixed a problem with drag&drop when restarting the skins engine.

* modules/control/hotkeys.c, src/libvlc.h, include/vlc_keys.h: added hotkeys for jump actions.

 * fixed timing with vobsubs

 * added support for matroska files with embedded spu tracks, what the
   matroska people call VobSubs

* modules/gui/wxwindows/preferences_widgets.cpp: attempt at optimizing KeyConfigControl which is really slow on wxGTK.

* modules/gui/wxwindows/preferences.cpp: restored the old size of the preferences panel... it is big enough already.

* modules/codec/ffmpeg/ffmpeg.c: CODEC_ID_MPEG2VIDEO only supported from version 4676.

* modules/codec/ffmpeg/ffmpeg.c: CODEC_ID_MP3 is only available on recent ffmpeg versions.

* modules/gui/wxwindows/*: fixed breakage.

   - splitted the enormous playlist.c file
   - implemented a better item group system: groups have a name
     and must be created before use by
      playlist_CreateGroup( p_playlist, "newgroupname")

* modules/misc/sap.c
   - Create our own playlist group ("SAP") and use it

* modules/access/slp.c
   - Create our own playlist group ("SLP") and use it

* modules/demux/util/id3tag.c
   - Trigger playlist update when we have parsed our tag

* modules/gui/wxwindows/interface.cpp
   - Fixed the about box by using vlc_wraptext
   - Added the simple open and the streaming wizard icons
           *** Icons need to be changed ! ***
   - Added the visualization to the extended gui

* modules/gui/wxwindows/preferences.cpp && include/vlc_help.h
   - Enlarged the window to fit the wrapped text
   - Added help for audio encoders

* modules/gui/wxwindows/stream.cpp  & open.cpp & include/vlc_interface.h
   - Created a "streaming wizard" window (3-step streaming)

* modules/gui/wxwindows/iteminfo.cpp:
   - Group change is now based on the name

* modules/gui/wxwindows/playlist.cpp
   - Added author and group columns to the listview
   - Redesigned the window
   - Added the Sort menu with several criteria (title, author, group)
   - Added up/down buttons to move an item in the playlist
   - Added the group menu to enable/disable a group in an understandable way


TODO:
-----

* playlist core :
   - Implement advanced sort capabilities  (multi-criteria)
   - File format to save the new features
   - export playlist (to M3U, eg)
   - more robust group creation (duplicates check, ...)

* wxWindows playlist:
   The idea of a treeview seems impossible, because of wxWindow's treeview,
   that don't allow multi-selection, and, as far as I know, multi-columns.
   - Provide a frontend to advanced sort (when it's done :-) )
   - Allow moving items by drag & drop (well, if possible, haven't checked yet)
   - Allow moving several items at once
   - Customizable listview (ability to remove/move columns)
   - Find a solution to the focus problem
     (when you change track, the selected one scrolls at the
      bottom of the visible screen)

* wxWindows interface:
   - New icons, our icons begin to get old and not so pretty
   - Find a solution for the volume bar (nobody understands what it is)

* modules/video_output/directx/events.c: fixed key modifiers detection.
* modules/gui/wxwindows/*: removed the sorted flag from a couple of comboboxes.

  And this is no final solution, i think it should be handled in VLCApplication.

* ALL: improved hotkeys support.

 * fixed freetype module on big endian systems
 * removed a nasty debug line
 * cosmetic fix

* modules/video_output/x11/xcommon.c: hotkeys handling cleanup and support for ctrl/alt/shift modifiers.
* modules/gui/wxwindows/preferences_widgets.cpp: correctly select the active hotkey (needed on win32).
