Audio and Subtitles submenus into the Audio and Video menus.

    variables.

    --enable-alsa was specified.

                          World domination ... is at hand.

    the optopt variable instead of the current value of optind (Closes: #148).

* src/video_output/video_output.c: we were still using free instead of
   vout_DestroySubPicture in one place.
* modules/codec/spudec/parse.c: we now make sure we don't add several times
   the same highlight callback.

  * SGML sucks, this is absolutely ugly, please reread

* modules/codec/spudec/spudec.c, modules/codec/spudec/text.c: fixed the
   race condition between spudec and vout. This patch may not be all that
   nice because it does a lot of vlc_object_find() but it is the only
   solution I've been able to come-up with.
   Oh and I didn't fix the memory leak caused by the font when using text
   subtitles. If the vout changes while the spudec is running then we don't
   unload this font.

  - fixed a warning about parentheses

  - we close the video window after a video is done playing.

* src/video_output/vout_subpictures.c: fixed a few race conditions that
   were triggered by the dvdplay plugin.

* modules/codec/mpeg_video/headers.c: fixed non-initialized variable in
    PictureDisplayExtension(). This does also fix problems with the dvdplay
    plugin and menus with still pictures.

* modules/gui/macosx/intf.m: one of the threads wasn't in real-time
  priority !!!
* include/vlc_threads.h: tuned up OS X priorities

project: the source files were included in the Resources. No more.

    the title and chapter dialogs when DVD menus are activated.

* modules/gui/gtk/*: changed the disc open dialog to allow for title and
   chapter 0. When title or chapter 0 are selected, they do not appear in
   the MRL.

    in case the input dies before we even spawned our dvdplay interface
    (Closes: #141).

* include/vlc_threads.h: VLC_THREAD_PRIORITY_VIDEO equals
    THREAD_PRIORITY_BELOW_NORMAL under Win9x/Me.

* modules/demux/ogg.c: bug fix when switching between vorbis channels.

 * modules/gui/macosx: started getting rid of p_intf->p_sys->p_input
                       and using p_playlist->p_input instead.

* modules/access/dvdplay/access.c: fixed subtitles with the dvdplay plugin
    (closes #122).
* modules/access/dvdplay/es.c: check "audio-channel" and "spu-channel" user
    settings (closes #122).

    messages that were lying around.

    has been overriden by the user (Closes: #79).
  * ./modules/access/dvd/access.c: renamed "dvd-css-method" to "dvdcss-method".
  * ./modules/*: fixed a few capitalization issues.

* modules/gui/wxwindows/open.cpp: minor bug-fix + allow user to select
   title 0 when using the dvdplay plugin (title 0 = menu).

    DATA_PATH.
  * ./modules/gui/wxwindows/*.cpp: fixed minor warnings.

  * ./po/*: fixed spelling errors in pofiles.
