* small fix for the config file. The parser assumes that the config file is
divided into sections (a section is the config data for a plugin and begins
with something like [foo]), so the comment for the beginning of the section
must be after the section marker and not before.

If you want to illustrate the problem (without this fix):
- save vlc's config
- exit from vlc and remove for example the dsp plugin (rm plugins/dsp.so)
- resave vlc's config
and now look at the end of the config file, it's all screwed up.

Video window now returns to correct size and position after toggling
full screen.

  * ./configure.in: more modules are plugins.
  * ./src/misc/configuration.c: changed ~/.VideoLan/vlc to ~/.videolan/vlcrc,
    and a few cosmetic changes (sorry Gildas for the butchery).
  * ./plugins/chroma/i420_rgb16.c: C version of the I420 to RV15/16 chroma.

* This the last piece of the new configuration module. You can now save your
configuration options (only from the gtk/gnome interface for now). The config
file will be saved as ~/.VideoLan/vlc

It's not quite yet finished (well there are a few small details to sort out),
but I'm going away for the week-end and I wanted to commit this before so you
can all have a play with it :)

  * ./plugins/spudec/spu_decoder.c: we now analyze the subtitle image
    data to find the border color and the inner colors when there was
    no way to find the palette data (network stream).

  * ./plugins/mpeg_system: fixed a parsing bug I introduced yesterday.

  * ./Makefile: fixed OS X vlc.app compilation dependencies.
  * ./configure.in: fixed the endianness check under Solaris.

  * ./src/input/input.c: strings are now initialized to "" instead of NULL.

  * ./plugins/spudec/spu_decoder.c: we now properly support the subtitle
    palette information we get from the DVD. Subtitles rox !
  * ./src/video_output/vout_subpictures.c: removed all DVD-specific routines
    and put them into spu_decoder.c.

*Move iec958/spdif encapsulation from ac3_spdif to aout_spdif.
It will eventually allows to use ac3_adec or a52 for spdif output.

*Remove an ugly loop in aout_spdif.

-Fixed chapter selection at startup.

*p_es->p_demux_data is available in p_config->p_demux_data so that the input
can pass information directly to the decoder.

*First application: aspect ratio for DVD is read from the ifo (should fix
the buf with aspect ratio in anamorphic DVDs).

*The DVD plugin also copy the spu yuv palette in p_demux_data so that the
spudec can display subtitle with the right color (sam !).

*Removed duplicate code and useless lock in gtk.

* Fixed EOF and Stop segfault in VCD input : input_BuffersEnd was being
  called two times

* a52 plugin updated to use liba52-0.7.3 ( which is now available on debian :)

*New configuration option to choose audio output format at runtime.
It allows to select spdif pass-through decoder with --ac3_adec and to
remove the ugly b_ac3 in main.h

As a consequence --spdif doesn't work anymore: you should use --ac3_adec pass

*Fixed a typo in main.c

*Return the option name in error message for unknown option intead of the
argument.

* gtk config interface modified so you can only have one instance of a plugin
    config dialog box displayed at one time.

* oops, forgot to check the gnome interface before my last commit.

* New GTK configuration interface. This interface is generated dynamically
  at run-time from the configuration data contained in each plugin.
* config_PutPszVariable and config_GetPszVariable are now thread safe.
* Few modifications/optimizations to the config module.
* Got rid of all the _VAR macros in config.h

This is the first version of the GTK configuration interface. There are still
a few raw corners and a fews things left to do, but it basically does what
I wanted.
Constructive comments like it sucks or it smells rotten fish are of course
very welcome. And if there are GTK gurus out there, please don't hesitate to
add your touch.

I also started to add usefull comments to the configuration options but I'm not
really good at this kind of thing so if people want to help, they can finish
the job. For this look at all the *_LONGTEXT macros at the top of main.c

(PS: Translations will also be appreciated but not right now as the interface
will likely change again in the few coming days)

*Fixed EOF segfault at end of DVD

*Buffer manager is renintialised at area change.

  * ./plugins/dvd/dvd_access.c ./plugins/vcd/input_vcd.c: we now exit more
    cleanly on initialization error.

Rewrite most functions in DVD plugin. Some old bugs might have been
solved in the operation. The plugin some be more readable now, and
should produce fewaer segfaults (I hope so :p)

  * ./src/interface/main.c: disabled the GNOME segfault dialog in debug
    mode. We want nice, clean segfaults, with huge core files and a lot
    of rattle noise.

*Take the lock on stream in VCDInit. PLease test, as I don't have any VCD
to do it.

  * ./plugins/ac3_adec/ac3_parse.c: ac3dec is now less verbose.
  * ./src/interface/interface.c: fixed a deadlock when seeking the
    stream using the keyboard arrows.

*Removed an occurance of former angle item in gtk.

*Fixed a bug in ES management introduced lately in DVD/DvdRead.

*Beginning of reorganisation in DVD plugin source files, in order to try to
make it easier to understand. There is some work left though :p.

*Decreased the score for VCD plugin, as the VCD demuxer was used even
for DVD :p. It should make autodetection work.
Some comment:
-I think that VCDInit should make a test on the access plugin and be launched
only if the access plugin is VCD,
-VCDOpen shouldn't set p_input->b_error: if it fails we just try another
module,
-PSRead doesn't need to be duplicated anymore: input_ReadPS is now available
for plugins (cf Christophe's commit).

Please comment around that: I'd like to know if the behaviour I've described
is the one everyone expects.

Enjoy my new bugs :p

* Modified vcd input for the new input III.
* Still have problems with end of tracks.
* Modified the command line, as stef did for the DVD :

 [vcd:][device][@[title][,chapter]

 Note that chapter support is not yet implemented.

Dvd demux was no longer selected under win32

* Dvd angle is now handled through a program structure, so that the interface
needs nothing specific to change angle.

* Fixed a bug in clock management where ES without a program couldn't get
timestamped.

*Fixed program management in gnome/gtk. Program now also appears in popup.

*In interface, only display ES associated with the selected program, or with
no program at all.

* fixed typo in the win32 change to the input parser.

for BT ;
* --6 and --4 options to force IPv6 or IPv4 (FIXME: it should be -6 and
-4 but I don't know how to do it with the new configuration module) ;
* Channel manager now uses a socket from the network plug-in and is more
portable (and probably broken, too :) ;
* input_ReadPS and input_ReadTS are now in mpeg_system.c to be more
easily reused by plug-ins other than mpeg_ps and mpeg_ts.

That's all for tonight.

* this time I actually commited the win32 modif to the input parser ;-)

* We now make sure the aout plugin buffers always contain between
AOUT_BUFFER_DURATION/2 and AOUT_BUFFER_DURATION*3/2 worth of audio.
This should solve the audio buffer underruns.

* fix for the bug in input when filename contains a '@' character.

* simplified the win32 specific changes to the input parser. ( I think
we can safely assume that no access plugin name will have a length of
one character)
