Encapsulation des pthread qui sont maintenant remplac�es par les vlc_thread.

Toutes les r�f�rences aux pthread que ce soit les thread, les mutex ou
les variables conditionnelles, ont �t� remplac�es par leur �quivalent
vlc_thread. Les vlc_thread sont une version tr�s simplifi�e des pthread et
fonctionnent exactement de la m�me fa�on. Ceci devrait grandement faciliter
le portage vers d'autres OS.
