Options

. fix� une erreur de syntaxe dans video_fb.c 

 . *3dfx* devient *glide*
 . suppression de tabulations dans quelques fichiers
 . suppression des 2 warnings dans sam_synchro
 . video_* devient vout_* quand ce sont des m�thodes de vout
 . tentative de correction de la d�tection de MMX pour BeOS
 . nouvelle option vlc_vout_method (faute de mieux pour le moment)
 . modification du Makefile pour supporter plusieurs VIDEO_*

dor�navant on peut compiler plusieurs output diff�rents dans le
client. la pr�f�rence se fait dans l'ordre x11, fb, ggi, glide...

si on le compile avec x11 et fb, par d�faut il se lancera en X.
pour le lancer en framebuffer :
./vlc vlc_vout_method=fb

(il faut que je proprifie un peu le choix de l'output, et que je
facilite l'ajout d'un nouveau vout_*)
