. fixed the bug-that-made-the-vlc-segfault-on-exit, which means that
   more than ever, � le client ne segfaulte pas �.

 . there was still a problem upon quitting: sometimes the null packet
   wasn't big enough to reach a decoder breakpoint, so I now create 10
   of them (since I can't make it bigger) to be sure. Meuuh, what do
   you think ?

 . fixed the Makefile to spare a few variables here and there.

 . reduced module hide delay, removed loading of the audio output
   plugins since they are now modules.

 . changed a few intf_Msg to intf_DbgMsg, and added "vout:", "intf:",
   and so on in a few other messages.

 . removed unused includes in the idct modules.
