* ALL: got rid of *_Probe functions because most of them were duplicates
    of the real _Init or _Create functions. That's 1000 lines of code gained.
  * ./src/misc/modules.c: we try not to keep the global lock in module_Need,
    which should speed up output spawning.
  * ./plugins/dummy/input_dummy.c: fixed vlc:quit command.
  * ./plugins/gtk/gtk_playlist.c: compilation fix.
  * ./plugins/macosx/*: preliminary fixes for the vout4 port.

   Notes on the *_Probe eradication:
  o I probably broke the DirectX video output, because of the "must init and
    run in the same thread" issue. I'll fix this ASAP.
  o Subtitles are broken (or at least, pretty ugly) in RGB mode.
  o The input plugins still have *_Probe functions. This will disappear when
    meuuh is finished with the access plugins.
  o The decoder plugins still have *_Probe functions. This is probably not
    going to change, it looks OK to me.

  * ./BUGS: added a list of known bugs. Please add your findings!
  * ./MODULES: added a short description of each module. Maybe we should
    add more details to make this file really useful.
  * ./doc/bugreport-howto.txt: wishful thinking...
  * ./Makefile: added a workaround for the fact that .c files don't depend
    on <videolan/vlc.h>.
  * ./plugins/memcpy/memcpy.c: all memcpy modules are now built from the same
    single file.
  * ./src/interface/main.c: added the --nommx, --no3dnow, --nommxext, --nosse
    and --noaltivec options to vlc.
  * ./configure.in: removed the --disable-mmx option, now useless because
    of the vlc --no* options.
  * ./src/interface/main.c: fixed a crash caused by the memcpy module
    being released too early.
  * ./include/video.h: more vout4 changes, including margin support, more
    FOURCC formats recognized, transparent support of identical or almost
    identical FOURCC formats.
  * ./include/video_output.h: added a vout_Render function to video output
    modules which is to be executed before vout_Display.
  * ./include/common.h: this header is back.
  * ./plugins/chroma/i420_rgb.c: planar YUV 4:2:0 to packed RGB conversion
    functions, mostly taken from vout3's yuv functions, but heavily modified
    to use FAST_MEMCPY and to handle image dimensions which are not multiples
    of 16. Not all functions have been written yet, though.
  * ./plugins/chroma/i420_yuy2.c: planar YUV 4:2:0 to packed YUV conversion
    functions, various targets such as 4:2:2 YUYV, YVYU, UYVY, or 2:1:1 YUYV,
    with accelerated MMX versions.
  * ./plugins/chroma/i422_yuy2.c: same as i420_yuy2.c but takes planar YUV
    4:2:2 pictures in input. With accelerated MMX versions as well. This plugin
    makes it possible to display 4:2:2 files on most video cards without the
    quality loss of 4:2:0 downsampling.
  * ./plugins/filter/*: thanks to the vout_Render function, all filters now
    output their data perfectly in sync.
  * ./plugins/dvdread/Makefile: fix to prevent unnecessary target rebuilds.
  * ./plugins/sdl/vout_sdl.c: support for YV12, UYVY, YUY2 and YVYU overlays.
  * ./plugins/x11/xcommon.c: support for I420, YV12, YUY2 and Y211 overlays.
