* modules/demux/asf/*: some clean up

usable, but it begin to give good result.

* include/vlc_threads.h: Avoid locking the interface,
* ALL: reworked all audio output plug-ins to correctly take into account
  i_channels. At present this is known to break OSS, probably others.

    the DirectX plugin (please test compilation).

  * ./modules/video_output/x11/xcommon.c: we transmit the click only at
    release time.

  * ./modules/access/dvdplay/intf.c: instead of probing the mouse on each
    loop iteration, we set a callback on the corresponding variables.

    can now use var_* functions from within your callback, they can even
    trigger callback themselves, to any level. The main restriction is that
    you shouldn't meddle with a variable that is already being triggered by
    the current thread (other threads will just wait).
  * ./src/misc/objects.c: fixed a deadlock in the "tree" command.
  * ./modules/misc/testsuite/test4.c: added a "callback-test" command to the
    rc interface to test callback loop detection and concurrent triggers.

    palette, implemented the "force display" command as forever-living
    subtitles, and reworked some code.
  * ./src/video_output/video_output.c: we increment the image date even if
    we are repeating the previous image, so that subtitles have a chance to
    get displayed.
  * ./src/video_output/vout_subpictures.c: ephemer subpictures don't timeout.

crates a little button next to the textarea that pops up a file open dialog
where the user can point and click on the file to select. It also drops down
a list of possible completions as the user types.

* Fixed a compile issue in the vcd plug-in,
* Fixed SDL behavior with > 2 channels.

    callbacks.

    under platforms without libintl such as Win32. Use --with-included-gettext
    to test. Might break compilation on systems I don't have access to.

    phase.
  * ./modules/video_filter/deinterlace/deinterlace.c: the bob method now
    flickers less thanks to a patch from Marian Durkovic <md@bts.sk>.

    we now release the variable lock before calling the command.
  * ./src/misc/threads.c: removed deprecated code.

* Fixed detection of VCD support under OS X.2.

* modules/access/vcd/*, configure.ac.in:
   - Major changes to allow reading vcd images directly from the hard drive
      (you need a .cue and .bin file).
   - Removed duplicated code by merging ioctl_GetTrackCount and ioctl_GetSectors.
   - Implemented necessary ioctls for Win9x/NT/2K/XP.

    vlc_mutex_need() and vlc_mutex_unneed().
  * ./src/misc/variables.c: implemented VLC_VAR_MUTEX variables.
  * ./modules/misc/gtk_main.c, ./src/libvlc.c: replaced named mutexes with
    named mutex variables.

and to prepare for OpenDML support.
Add new options :
  --avi-index force index creation.
  --avi-interleaved force method used for unseekable stream but need
interleaved stream and could lead to loss of audio/video synchro.

 * wav : demux for wav file( should work with raw pcm, mp3 or a52 stream ) but
untested under big endian machine(for pcm).

All are compiled by default.

Updated description.

    by making the spawned threads wait a bit longer.
  * ./src/misc/variables.c: added a usage count to the variables; trying to
    create a variable with the same name only increments its refcount.

  * ./include/main.h: removed p_vlc->i_status because it was not sufficient
    to represent all the possible states of p_vlc; each part should be tested
    separately upon destruction.
  * ./src/misc/objects.c: fixed a signed/unsigned bug that prevented creation
    of VLC_OBJECT_GENERIC objects.

  * ./src/misc/variables.c: added the VLC_VAR_COMMAND type which is simply a
    variable that stores a function pointer, and calls it when var_Get is
    called for it. The function argument is taken in val.psz_string.
  * ./src/misc/objects.c: vlc_dumpstructure and vlc_liststructure are no longer
    exported to the rest of the program; instead, they're VLC_VAR_COMMAND vars
    ("tree" and "list").
  * ./modules/control/rc/rc.c: moved a few commands to VLC_VAR_COMMAND vars.

    compiled yet because it uses the "command" variables I'm about to check
    in. They need to be typed in the rc interface for instance (-I rc). This
    module has two available commands: "signal <int>" which sends the given
    signal to the vlc process, and "stress [<int>]" which performs a series of
    object creation/lookup/destruction, variable creation/setting/destruction
    and thread spawning/joining tests. The optional argument for stress is an
    integer between 1 and 200 (the bigger, the heavier the tests; it may hang
    your machine at around 150, be careful).

It is kludgy, but it works ;)

 modules/gui/kde/*: only set variable the user actually have changed when
apply is pressed in the preferences window.

identical ! So I removed hacking.xml...

* configure.ac.in: fix for the mingw32 build. The gtk plugin may also need mingwex.
* modules/demux/mpeg/ts.c: added an #include <stdint.h> to make mingw32 happy when
   compiled with libdvbpsi.
* Makefile.am: fixed dependency problem with share/vlc_win32_rc.rc.

* configure.ac.in: fix for the mingw32 build. We check if we need to explicitly
   link with the mingwex library (needed for dirent support with new mingw32
   runtimes).

Sound is yet choppy (I don't know why).
