* ./include/configuration.h: renamed MODULE_CONFIG_* macros into
CONFIG_*.
* ./include/configuration.h, ./plugins/gtk/gtk_preferences.c,
./plugins/filter/transform.c, ./plugins/filter/distort.c,
./plugins/filter/deinterlace.c: added an ADD_STRING_FROM_LIST()
configuration macro.
* ./include/modules.h, ./include/video_output.h,
./src/video_output/video_output.c, ./plugins/filters/*: added a
VOUT_FILTER capability. Having a clear distinction between VOUTs and
VOUT_FILTERs allows us to get rid of ugly hacks. The filters are also
stackable now (use --filter=foo:bar:foo etc..).
* ./include/configuration.h, ./src/libvlc.h, ./src/libvlc.c: clean-up +
added an ADD_USAGE_HINT() configuration macro.

  * ./plugins/filter/deinterlace.c: the blend mode is now a lot smoother, but
    also a bit slower, so I also kept the old version, optimized it, and
    called it "mean".

    "discard" which is very CPU efficient, and "blend" (yes there used to be
    a "blend" method but it's now called "linear". Don't ask) which loses some
    vertical resolution but discards the mice teeth effect. Information was
    found on http://www.100fps.com/index.htm.

    We now have "discard", "blend", "bob" and "linear".

    ./plugins/macosx/intf_vlc_wrapper.m: preliminary OS X compilation fixes.

    implementation to avoid races, by using SetEvent instead of PulseEvent.

  * ./plugins/xosd/xosd.c: configuration options

    to be still crashing.

  * ./plugins/text/rc.c: fixed the "a" command.

  * ./src/playlist/playlist.c: fixed an off-by-one loop error.

    and vlc:quit work again.
  * ./src/playlist/playlist.c: when a new target is added, for instance through     the "File" menu, it is automatically played.

    vlc_object_destroy (idea from stef).
  * ./po/pl.po: updated polish translation, thanks to Arkadiusz Lipiec
    <alipiec@adrenalina.pl>.

  * ./src/misc/objects.c: we do not hang on attempt to destroy an object with
    a non-zero reference count, but we still complain.
  * ./plugins/gtk/gtk_control.c, plugins/gtk/gtk_playlist.c: most controls such
    as play, pause, stop, next, fast etc. work again.
  * ./plugins/gtk/gnome_*: got rid of lots of useless wrappers which were a
    workaround for a bug in Glade. Instead, bootstrap.sh does the Glade fixes.
  * ./plugins/ffmpeg/ffmpeg.c: if there is already a video output with the
    appropriate properties, we use it.

and they are used nowhere.

  * ./plugins/gtk/gtk_callbacks.c: fixed a segfault when switching to
    fullscreen from the popup menu.
(from v0_4_1_branch)
  * ./plugins/gtk/gnome_callbacks.c: fixed a crash when activating preferences
    from the popup menu.
  * ./plugins/gtk/gnome.glade: added lines this #@%$! Glade had munched, fixes
    a segfault in the Gnome popup menu when toggling the interface.

  * ./src/interface/interface.c: interfaces are no longer attached only to
    p_vlc.
  * ./src/libvlc.c, ./src/misc/modules.c, ./src/playlist/playlist.c,
    ./src/input/input.c: improvements in the playlist handling (not quite that
    yet though).
(ported from v0_4_1_branch)
  * ./configure.in, ./plugins/mpeg_system/mpeg_ts.c: fixed libdvbpsi handling.
  * ./src/misc/configuration.c: fixed the --nofoo option handling.
  * ./src/interface/main.c: fixed two compilation warnings under Solaris.

* ./plugins/win32/waveout.c: waveOutUnprepareHeader() was never being
called. This should fix the memory leak some people reported when using
the waveout plugin.

  * plugins/a52_system/Makefile, plugins/a52_system/a52_system.c: a52 input
    module.
  * plugins/ac3_spdif/ac3_spdif.c: added a little mwait to avoid a flood from
    the a52 input module.

Note: the new module aims at reading ac3 streams but it works only with the
ac3_spdif "decoder" since it is the only one which dates each frame contrary
to the others which can't avoid a flood from the input module.

  * ./plugins/motion/motionmmx.c: MMX motion optimizations courtesy of
    Vladimir Chernyshov <greengrass@writeme.com>.

  * ./plugins/spudec/spu_decoder.c: we now use FIND_ANYWHERE to find a vout.
(ported from v0_4_1_branch)
  * ./plugins/dvdread/dvdread.c: disabled the dvdread plugin because it
    currently sucks.
  * ./src/misc/configuration.c, ./src/interface/main.c: we now accept --nofoo
    and --no-foo as negations for --foo. Also, the --help output is nicer.
  * ./plugins/qnx/vout_qnx.c: QNX compilation fix.

* ./include/vlc_common.h: got rid of i_thread in VLC_COMMON_MEMBERS.
