./src/libvlc.h: Default to en0 instead of eth0 under Darwin

* ALL: Splitted the directx plugin into an audio and video module.

  ./modules/gui/macosx/open.[mh]: Open Target code

  * ./src/misc/objects.c: structure_lock is now local.
  * ./src/misc/threads.c: implemented named mutexes which provide a handy
    way to protect data across plugins which might be sharing the same
    resources. Thread-unsafe libraries come to mind, but we can imagine
    using a named mutex for configuration files, or special devices.
  * ./include/main.h: removed global_lock because of vlc_mutex_need, removed
    p_global_data because it was never used, removed structure_lock because
    it did not belong here.

    the video output is initialized, we wait for a while before giving up;
    also changed the code so that it probes all interface objects rather than
    the first one it finds.

  * ./modules/misc/testsuite/*: moved the null module into three test modules
    that are only built when --enable-testsuite is activated. This directory
    can be a good place for compilation tests or performance benchmarks.

* src/misc/threads.c, src/misc/win32_specific.c, include/interface.h: fixed typos.
* configure.ac.in, modules/gui/gtk/gtk.c: Added a NEED_GTK_MAIN macro to the compiler
   flags for the gtk module. When this macro isn't defined, then the gtk module
   doesn't make use of the gtk_main module. I had to do this change because the
   gtk_main trick can't work on win32 and render the whole gtk interface unusable.

    locales breakage.
  * ./src/libvlc.c: libvlc understands the VLC_VERBOSE environment variable,
    to be set between 0 and 4. Default value is 0 for a program using libvlc,
    but vlc sets it to 1 by default.
  * ./src/misc/configuration.c: -v now works the old way (-v, -vv, -vvv) as
    well as the new way (-v0, -v1, -v4). -v1 is the same as -v, and -v0 is
    the same as -q (quiet). Hope it's all understandable.

* FAQ: updated FAQ with config file issues.
* configure.ac.in: use -mms-bitfields instead of -fnative-struct for
   mingw32 gcc-3.x.
* include/interface.h, modules/misc/dummy/interface.c, modules/misc/logger/logger.c,
   modules/control/rc/rc.c: Display message on Win32 explaining how to get
   back to the GUI mode.
* src/misc/threads.c, include/vlc_threads_funcs.h: ignore the
   win9x-cv-method config option on WinNT when fast-mutex is not enabled.

    p_libvlc, and each p_vlc is a child of p_libvlc. Reasons for this are:

     o the module bank and the message bank only need to be initialized once,
       which gives faster loads when multiple instances of libvlc are used,
     o we allow the possibility of different p_vlc sharing objects, for
       instance the audio output,
     o the CPU detection is only done once.

    This patch is not polished yet, but I cannot do any intensive tests for
    the moment because of a bug somewhere that leaves audio output objects
    lying here and there which needs to be investigated first. The current
    major issue is that the module bank is no longer freed.

 interface.cpp, interface.h: create a messages window, and add menu iten to
show it
 Modules.as: build messages window
 ui.rc: menuitem to show messages
 preferences.cpp: fixed typo in comment

    version detection not to work properly.

    really possible other than patching/upgrading automake. This happens for
    automake 1.6.0 and automake 1.6.1.

       (always re-run bootstrap when configure.ac.in has changed).

to select which interface to use for multicast sockets.

new ones.

Playlist is yet broken (maybe others things too)

    and gnome-vlc packages.
  * ALL: updated .cvsignore files to properly ignore automake files.

  * ./mozilla/vlcplugin.cpp: javascript support for the Mozilla plugin.
  * debian/rules: the A52 module is now in a separate package.

  * ./src/libvlc.c: if items are specified in the commandline, run the playlist.
  * ./src/vlc.c: don't rely on internal vlc types (mtime_t).

* ALL: Fewer overhead when resampling.
