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.

* src/libvlc.h: spelling error
* include/ninput.h: There should not yet be a Subtitles section in Doxygen
* src/input/subtitles.c: Doxygen comments for this file

* Added the new cinepak and msrle codecs as well as some other forgotten stuff

* modules/codec/subsdec.c: cleaned up and ported the text subtitles decoder to the new decoder api.

Implementing new PDA User Interface design using the GTK2 widget set. This interface is currently in a rewrite and is currently unuseable. However:
- it compiles ;-)
- will have more UI assets to tweak with, then the old interface had
  to name a few: supports stream out, camera's through v4l, use preferences,
  manage playlists, play audio/video local and from a network source
- is not functional (yet)

So expect more functionality to come in and the necessary bug fixes.

* modules/codec/a52.c: fixes and simplifications.

* modules/demux/ogg.c: had mistakenly got rid of the old i_dts = i_stop_date hack for text subtitles.

* modules/stream_out/transcode.c: get the mp4v vol data from the encoder. This will make the mp4 muxer happy transcoded mp4v.

* include/vlc_block_helper.h, modules/codec/a52.c: same as thedj ;)

* include/vlc_block.h, modules/codec/libmpeg2.c: re-added the discontinuity flag in block_t and re-enabled the discontinuity gestion in the libmpeg2 codec.
* include/vlc_block_helper.h: implemented bytestream reading helper functions for chained blocks.
* modules/codec/a52.c: modified to use the bytestream reading functions.
  The flexibility added by these functions makes the code simpler and better at detecting synchro code emulations.

* modules/misc/freetype.c: i_render_height and not i_window_height.

* modules/mux/ogg.c: always backup the vorbis/theora headers so we can resend them if we close/reopen the stream (chaining).
  fixes for text subtitles muxing.
* modules/packetizer/copy.c: support for text subtitles.

* include/os_specific.h: oops, fixed my last commit.

* include/os_specific.h, src/libvlc.[c,h], src/misc/win32_specific.c: new win32 specific option (--one-instance) to have only one instance of vlc running at once.
 Running another vlc (with --one-instance as well) will only transfer the requested playlist items to the first instance.

 * changed project name from 'vlc' to 'VLC'
 * excluded src/extras from the documentation
src/misc/variables.c, include/variables.h:
 * Doxygen-documented most of the vlc variables code

* modules/mux/ogg.c: proper fps and ogg packet granulepos when embedding mp4v/div3 (mplayer can play the file now).

* modules/codec/theora.c: don't forget to delete the sout instance.
* modules/mux/ogg.c: fix for embedding theora in Ogg.

* modules/mux/ogg.c: each ogg stream has to be cleared in OggCreateHeader().
