report).

- fixed read after freeaddrinfo() bug,
- removed extraneous debug messages

* modules/access/screen.c: new screen capture access module. Only X11 for now but should be straight-forward to adapt to other platforms.

    to trigger AltiVec optimisations in our generic code.

 + contrib/src/Makefile: build more libs on BeOS, use libdts' svn
 + Makefile.am: fixed BeOS packages generation

* modules/video_output/directx/events.c: removed unused code.

 + extras/contrib/src/*: build libmpeg2 w/o mmxext and 3dnow on BeOS
   (buggy compiler)
 + modules/gui/beos/*: quick compile fixes
 + modules/video_filter/deinterlace.c: require mmxext instead of mmx
 + Makefile.am: on BeOS, build a VLC bundle a la OS X

* modules/video_output/x11/glx.c: OpenGL context is initialized in pf_init() because of threading issues.

* modules/video_output/opengl.c: new platform independant OpenGL vout (uses an "opengl provider" module).
* modules/visualization/galaktos/*: uses the new "opengl provider" module.

 don't have it

   simple interface to create and use OpenGL windows
 * modules/video_output/x11/glx.c: the GLX vout now implements the
  "opengl provider" interface
 * modules/visualization/galaktos/*: no more dependency on GLX: we use
   the generic opengl provider interface instead.
