* 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)

-replaced setenv with putenv

-fixed a bug in gtk.

* added network to the list of the plugins directories in Makefile
* small bugfixes

 * Fixed DVD input under Win32.
 * Fixed input parser under win32, chich couldn't understand that
c:\windows\bureau is a valid file and doesn't need to be accessed with
the plugin 'C' :-)
 * BTW, I added myself in the AUTHORS file :)

  * Got rid of int_types.h and did a few changes Ipkiss will need. Hope I
    did not break other platforms.

* fixed compilation problem related to ssize_t

 * Various Win32 compilation fixes.
 * DVD compiles, but doesn't work yet.
 * Fixed some typos in my previous Win32 multicast commit

   * ./plugins/dummy/input_dummy.c: fixed `vlc vlc:quit'.
   * ./src/input/input.c: initialized uninitialized variables.

*Forgot a header.
