between sound quality and speed

* INSTALL.win32, include/vlc_config.h, src/libvlc.h: changes to reflect the
   fact that libdvdcss now needs a colon after the DVD drive letter (on Win32).

* src/misc/messages.c: on Win32 only use fflush() if in debug mode.

* src/misc/win32_specific.c: try to raise the our process priority slightly
   above normal. This prevent us from suffering too much from normal activity
   of the OS.

* modules/access/http.c: don't crash, but complain on non http/1.x streams.

* modules/codec/spudec/*: modified the spu decoder to handle text subtitles.
   Only one format of text subtitles is supported right now but we should be able
   to expand this by modifying modules/codec/spudec/text.c.
   Most of this work comes from by Andrew Flintham ( thanks a bunch Andrew :).

* share/font-eutopiabold36.rle: new font for the text subtitler, courtesy of
   Andrew Flintham.

* AUTHORS: added Andrew Flintham to the authors file.

* modules/demux/ogg.c: modified the ogg demuxer to handle subtitles.

* modules/codec/ffmpeg/*: modified the ffmpeg decoder to always keep the last decoded
   frame linked.

  * ./modules/codec/spudec/parse.c: implemented subtitle cropping and
    temporarily disabled subtitle cropping.
  * ./modules/codec/spudec/render.c: split RenderSPU into chroma-specific
    functions.

    chapters).
  * modules/gui/gtk/gtk_callbacks.c: added some locks to the
    navigation functions

    endianness fixes, spelling fixes, reworked return values usage, used
    C99 types.

  * ./src/libvlc.c: fixed a bug causing all commandline targets to be ignored
    for playback except the last one.
  * ./modules/codec/dv.c: we detach p_vout before quitting.
  * ./modules/codec/xvid.c: fixed image corruption, added a direct rendering
    option which doesn't work yet.

* modules/demux/avi/*: should theoretically fix the endianness issues with
   the avi demuxer.

    from xvid.org; compile with --enable-xvid --with-xvid-tree=..., run with
    --codec xvid,any (the priority is lower than ffmpeg's for the now).

    todo list: direct rendering, better buffer handling, see why only I frames
               are rendered OK here... probably more.

* modules/demux/ogg.c: should theoretically work on Big Endian machines now.

* All: moved the check for "video" and "audio" config variables to
   input_SelectES(). That allows --no-video and --no-audio to automagically
   work for all demuxers.

    GetFirstPES in favour of input_ExtractPES/input_DeletePES calls.

* modules/codec/ffmpeg/*: modified the ffmpeg video codec to use direct
   rendering when possible.
   Use BITMAPINFOHEADER from include/codecs.h + got rid of Little Endian
   translations that were already done in the demux.
* modules/demux/avi/* modules/demux/asf/*: Use BITMAPINFOHEADER from
   include/codecs.h.

  * ./mozilla/npvlc_rc.rc, ./mozilla/vlcplugin.h: added the Ogg mime type to
    the Mozilla plugin properties.
  * ./debian/control: added libogg-dev and libvorbis-dev dependicies to the
    Debian build script.

* include/codecs.h: new header file to store information shared by decoders
   and demuxers, like the BITMAPINFOHEADER structure for instance.
* modules/demux/ogg.c: the ogg demuxer should now work nicely with ogm files
   (including for the video). It has only been tested with a few streams
   produced with dvd::rip and ogmmerge though.

* modules/demux/ogg.c: we now correctly handle multiple vorbis logical streams
   in ogm files.
* modules/codec/vorbis.c: small bugfix.

* modules/demux/ogg.c: small fix to avoid crashing when find unknown codecs.

* modules/demux/ogg.c, modules/codec/vorbis.c: seeking in an ogg stream is
   working fine now, + misc other improvements.

debian/rules: update the location of libgnome_main_plugin.so and
libgtk_main_plugin.so. Added the ui.rc file to the kvlc package. All debian
packages seem to build now (even though there were some warnings)

* src/video_output/video_output.c: small change to avoid using floating point
   registers in the video ouptut routines.

* modules/audio_output/directx.c: forgot an aout_BufferFree().

* src/audio_output/common.c, include/aout_internal.h: added a new function
   aout_FifoFirstDate() that allows the aout plugin to schedule the first
   play.
* src/audio_output/output.c: fixed another problem affecting the audio quality.
* modules/audio_output/directx.c: improvements. The buffering scheme has been
   changed to be less affected by temporary starving. We also schedule the first   sample to play.

    been modified. Maybe we'll need the other type, too, but this change will
    make things simpler in aout3.

  * ./src/playlist/playlist.c: removed two unused variables.
  * ./src/misc/modules.c: removed a debug message I had forgotten.
  * ./src/misc/modules_plugin.h.in: fixed a typo (thanks bozo).

* modules/codec/spudec/spudec.c, modules/codec/spudec/parse.c: fixed a couple
   of problems introduced with the recent changes to the bitstream facility.
* src/audio_output/output.c: fixed a quite annoying bug in aout3 that was
   triggering unnecessary trashing of audio frames.

   uses it
 - clean up

  * ./bootstrap: fixed calls to $(LINK) which had duplicate -o options.

    an error (value < 0) if the variable does not exist.

    which are a generic use of the realloc/memmove/index++ scheme we use for
    dynamic arrays.
  * ./src/misc/variables.c: properly free the choice list upon variable
    destruction.

* modules/codec/ffmpeg/audio.c: compilation fix for ffmpeg builds < 4618

* configure.ac.in: libvorbis depends on libogg.
* include/vlc_threads.h: changed the different threads priorities to optimize
   audio and video quality as well as responsiveness.
* modules/audio_output/waveout.c modules/audio_output/directx.c: waveout and
   directx will now use the float32 format if available. Various tweaks for
   better performance.
