* modules/misc/sap.c: added sanity checks and more coding style fixes

* src/video_output/video_output.c:
  Video filters can now be enabled on the fly (vout is respawned)
  You need to var_Set( p_vout, "filters", psz_yourvalue)
      for this

* modules/gui/wxwindows/interface.cpp : Enable the adjust filter on the fly

* Makefile.am: forgot to include vlc_block_helper.h

* modules/demux/mp4/*: Added support for the "wave" tag used in mov files with aac.

* modules/gui/wxwindows/*: compilation fixes for the unicode version.
   made the "Extended GUI" option a checkable menuitem.

  src/playlist/playlist.c:
     * Implemented a boolean b_enabled to disable a playlist item
     * Implemented the idea of group (p_item->i_group), that allows
       to enable/disable and to sort some series of items
     * Implemented an unused (at the moment), psz_author field
     * Started to implement a new playlist format to store all of these

* modules/gui/wxwindows/interface.cpp:
     Added a hiddeable panel to put some important options.
     (Menu Preferences->Extra GUI)
     At the moment, we put the adjust filter and aspect ratio, and must
     decide what options we want here

* modules/gui/wxwindows/playlist.cpp
  modules/gui/wxwindows/iteminfo.cpp:
     Added "Enable/disable group button", options to enable/disable selection
     Added an item info dialog box

* modules/misc/sap.c :
     Added a sap-group-id option: the SAP playlist items are in a separate group
     (defaults to 42)

* modules/visualization/visual/effects.c:
     Minor coding style fixes

Todo:
-----

* Advanced sort (alphabetical and/or by group)
* Ability to load 0_6 playlists
* Really use the libid3tag

* src/input/input_dec.c: forgot to commit that with my last libmpeg2 plugin changes.

* src/video_output/video_output.c: fixed a recent patch that had been causing a lot of jerkiness in the video.

    + Better BeOS dynamic loader detection.
  * src/misc/modules.c:
    + Consistency fixes.

* modules/packetizer/mpeg4audio.c: ported to the new decoder api and added ADTS streams packetization.

    + As platform-dependant dynamic loader functions are no longer inline,
      moved them to modules.c which is their real place.
    + More verbose error messages on some platforms.

* modules/codec/mpeg_audio.c: fixes and improvements.
* include/vlc_block_helper.h: fix for an offset problem in block_SkipBytes() and block_GetBytes(). (This fixes the problems with the new mpeg_audio decoder/packetizer).

 * Increased size of and decreased margins around the section heading. It
   looks nice now.

* modules/access/vcdx/*: Brand new VCD input module using libcdio, libvcd and libvcdinfo. Courtesy of Rocky Bernstein.
* modules/access/cddax.c: Brand new CDDA input module using libcdio. Courtesy of Rocky Bernstein.
* modules/LIST: update.

    module loading to fail.

    loader.

* modules/gui/wxwindows/wxwindows.cpp: fix for the skins showing the popup menu even when left-clicking with the mouse.

* modules/packetizer/mpegaudio.c: updated mpegaudio to the new decoder api.
* modules/packetizer/mpegaudio.c: moved the packetizer with the decoder (they share most of their code).

* modules/codec/a52old/*, modules/codec/mpeg_audio/*, modules/codec/mpeg_video/*: got rid of deprecated decoders.

    + First try to detect the OS X native dynamic linker before falling
      back to dlfcn.h.
    + Enhanced the dlopen-style loader detection.
    + Added a check for HP-UX's shl_* functins.
  * src/misc/modules_plugin.h.in:
    + Support for the dylib dynamic loader on OS X.
    + Support for the shl dynamic loader on HP-UX.

* configure.ac: added --with-ffmpeg-faac for when using an ffmpeg which is compiled with faac support.
* modules/stream_out/transcode.c: added mp4a fourcc for MPEG AAC audio transcoding support.

modules/gui/wxwindows/preferences.cpp:
 * slightly modified layout of the window
   * The help text is now below the controls
   * Neither heading nor help text is inside wxStaticBox but rather
     separated from the controls with a simple line.
 * changed a lot of strech-factors, makes the dialog look generally more tidy

* modules/stream_out/transcode.c: get decoder specific info from the audio encoder (useful for MPEG AAC).

* modules/codec/cinepak.c: ported the cinepak decoder to the new api.

- cleanup of messages
- adding status events messages from frontend
- separated tuning for DVB-S, DVB-T and DVB-C into seperate functions.

  - Removed a dupe.
  - Added a 'L' commandline shortcut for loop and 'R' for repeat. There
    already is a 'Z' shortcut for random.
* modules/codec/subsdec.c: debug info.

Fix bug for DVB-T tuning. The code always used default upper and lower frequencies from DVB-S for DVB-T, but for DVB-T they could very well be different. Now using --lnb-lof1, --lnb-lof2 and --lnb-slof values are used by default instead. This make it overrideable on the commandline.
