Added netlist support.

Warning : it has not been tested. It just make no error at build time.

who thought it would be cleaner to put config in environment variables
correct what's wrong in my code).

 . now we only try to open plugins which are existing files

* Fixed a bug in AC3 initialization ;
* PS streams are now pre-parsed (this can take a while) if possible ;

./configure is required after this update.

Change vlan_server_ip to vishnou's ip (but vlans not working yet)

  - one line deleted (it was for debug, bozo.)

in a big buffer (a gift for Sam).

  - Quantic start in fullscreen fixed.

 . split the audio decoder into adec_generic, adec_layer1 and adec_layer2
    (no new code added)

 . additional fix for Layer 1 mono

   now vlc plays all of my 125 sample mpeg1 movies !

   Please try it with yours, and report non-working streams.
    (`file foo.mpeg' must report "system stream", not "video stream" in
       order to be playable with the vlc)

 . fixed audio syncword detection for mpeg 1 streams (hopefully)
    FIXME: can anyone confirm we can get rid of adec_byte_stream_next
    in audio_decoder_thread.c now that we have the new input ?

 . fixed Layer 2 Mono decoding.
    FIXME: who created freq_table ? what was the rationale for it, and
    where does it come from ?
    FIXME: how can we spare the extra DCT in audio_decoder.c:707 ? I'm too
    tired to think about it.

 . proposal: splitting audio_decoder.c in one file per layer.

    4:2:0 streams.
  - Removed vout code found in intf file to support fullscreen switching.
    Now only vout_SDL updates SDL data and intf only switch flags such as
    b_reopen_display and b_fullscreen in p_vout->p_sys.
  - Fixed a var name typo in input_programs.c which prevents vlc from
    compiling with --enable-debug option. (i_es_pid -> i_es_id :)

There's a segfault in the termination process due to sdl, I don't really
know what is the problem and I have to work today. Help me!

Good night suckers. I love you too :p

- "y" key switch between SDL and vlc YUV
- autodetection of Overlay support
- soon to come, colors :P

--Meuuh

necessary.
* Cleaned up decoder spawning.

* Moved b_discontinuity to pgrm_descriptor_t, cleaned up CRDecode
(needs some more cleaning for discontinuities)
* Added pf_new_pes in plugins

Netlist embryo :
 - pes netlist
 - data netlist

Still to do :
 - iovect netlist

It hasen't been tested yet.
Meuuh, could you tell me if it works ? ( if yes, gimme some more work :p )

Same changes that were made in the stbale branch ( FB_NOYPAN support )

Fixe la gestion des signaux

Generation d'un makefile presque correct pour les vieilles versions de make
Nettoyage: gestion des dependances pour les plugins, suppressions de pas
mal de redondances, options de compilations coherentes, etc...
