src/input/*: removed some testcode and some unnecessary debug messages

failing cleanly if it is >= 400

    extra plugin location.
  * ./plugins/text/rc.c: if stdin/stdout are not connected to a TTY, we
    don't launch the rc interface.
  * ./plugins/access/http.c: fixed a compilation warning.
  * ./src/misc/messages.c: cosmetic enhancements in the message output.

   As for video output 4, this breaks almost everything, but I'll slowly
  do what remains to be fixed during the weekend.

   Changes in vlc:
   ===============

  * vlc is now a very small program (20 lines) which uses the libvlc API;
   it is quite simple for the moment but can be extended in the future.

  * interfaces, decoders, video outputs, etc. are now almost the same
   objects (yes, I know, this is C++ redone in C) and are structured in
   a tree. More about this later, but basically it allows the following
   nice features:
    - several interfaces
    - several playlists with several outputs
    - input plugins spawning helper interfaces (will be used for DVD menus)
    - anything spawning anything; I swear there are useful uses for this!

  * libvlc can be used in other programs; I'm currently writing a Mozilla
   plugin for my employer.

   Things currently broken:
   ========================

  * most interfaces, most ports
  * the playlist handling (almost finished rewriting this though). This means
   no file can be played from the GUI, you need to use the commandline. This
   also means it segfaults at EOF, when exiting the program, and it sometimes
   refuses to open a file when asked to.

when closing a  networking stream instead of input_FDClose().  It is due
to WIN32  because we have  to call  closesocket() instead of  close() to
close the socket. The problem was  : windows did not leave the multicast
group when closing the socket.

  * input_ext-plugins.c : where is located the function
  * *.h : function declaration
  * udp.c, http.c : these modules now call input_FDNetworkClose()

  * ALL: internationalized all configuration strings.
  * ./src/interface/main.c: we now set LC_CTYPE to get the right charset.
  * ./src/misc/configuration.c: lots of simplifications in the code.
  * ./po/vlc/pot: updated translations.

* HTTP files now find the EOF (though HTTP input is still broken)

* Deleted non-working fullscreen menu item [OS X]
* udp and http no longer modify p_input->psz_name

  * ./configure.in: BeOS compilation fixes.
  * ./debian/rules: activated (broken) KDE interface.
  * ./plugins/access/http.c: fixed a segfault.
  * ./plugins/alsa/aout_alsa.c: fixed a segfault.

  * ./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.

* 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)

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.

- 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.
