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.

*Initiliaze p_access_module & p_demux_modules to NULL when input thread
in created.

  * ./po/no.po: Norwegian translation by Sigmund Augdal. Berd� ka p� t�t.
  * ./src/misc/modules.c: shortcuts for --intf work again, gvlc launches the
    Gtk interface, qvlc launches the Qt interface, etc.
  * ./plugins/fx/scope.c: we now have sound together with --aout scope.

*Removed numerous deadlocks.

*dvd and dvdread support for input III.

Dvdread is known to segfault at title change. I'm working on this.

- Major rewrite of the buffer core functions
- Modularity of access plugins (file, udp, http)
- Modularity of network stack (ipv4, soon ipv6)
- Autodetection of the type of stream

And a new killing feature : HTTP streams are now seekable.

Please note that dvd, dvdread and vcd plug-ins are broken and thus disabled.

  * ./plugins/mpeg_vdec/vpar_headers.c: we no longer crash when the next
    stream doesn't have the same image size as the previous one.
  * ./src/audio_output/aout_pcm.c: another overrun fix; please test.

  * ./configure.in: fixed a plugins/dsp.so compilation issue under OpenBSD.

  * ./plugins/dsp/aout_dsp.c: OpenBSD compilation fix.
  * ./src/video_output/video_output.c: fixed a segfault on exit.

  * ./src/input/input.c: BeOS network support (no idea if it works when you
    don't have BONE, though).

  * ./include/common.h: BeOS compile fixes.
  * ./plugins/beos/vout_beos.cpp: fixed BeOS video output.

* Fixed uninitialized variable in config_Duplicate()
* Fixed problem introduced in latest gtk commit

* forgot to add the declaration of server_port in main.c
* char pointers obtained by config_GetPszVariable need to be freed

Multicast now works under Win32, but this is a _bad_ kludge.

It still segfaults 4 secondes after the first frame, but, at least, I
can see two or three frames from MI2 :-)

I'd better used dvd_title or so but INPUT_TITLE_VAR is also used in
gtk_open.c and I can't find a neat way to prevent this, so I leave this
option in main.c.

  * ./include/threads.h: support for the State Threads Library, a userland
    threads library (http://state-threads.sourceforge.net/). Useless to most
    people, but can be handy to debug stuff. Activate with `--enable-st'.

*Adaptation to new configuration scheme for dvd, dvdread and spdif

  * ./plugins/lirc/lirc.c: removed CVS garbage.

  * ./plugins/gtk/gtk_menu.c: fixed a compile issue on IA64.
  * ./plugins/fx/scope.c: new toy plugin, an audio scope module.

    Each time I fix a bug in vlc I feel urge to code something useless. This
    one is very, very rough for the moment, probably buggy, slow, will crash
    your blender and reboot your fridge. Screenshot can be found here:
      http://www.zoy.org/~sam/vlc/vlc-scope.jpeg
    Activate with `--aout scope' (yes, it currently disables the real
    audio output... I'll fix this as well).

  * Replacement header for aout_common.h.

  * Forgot one fix in my previous commit. As usual.
