*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.

*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.
