MainInterface was the actual QWidget interface in VLC 3.0, now it's the
application context

only rename classes and files, no functional changes

The composition works as follow:

* Both the interface and the video are rendered in an offscreen window (using
  X11 composite extension)

* We register to damage event (x11 damage extension) to get notified when the
  content of the offscreen video window change. When we receive a damage event
  we ask the rendering part of the composition to refresh

* The interface is rendered in the offscreen surface using a RenderControl, when
  the interface do render, the composition is asked to refresh

* A dedicated thread is spawned to do the rendering, upon a refresh event it
  will take the pictures from the offscreen surface and blend them into the
  actual window using X11 render extension. Using a separated thread from Qt
  ensure that the rendering of the video will not be stalled if Qt thread is
  busy.

* The damage events are listened on a separate X11 connection and on a separate
  thread than Qt main thread (here the rendering thread). This allows to receive
  theses events independently from Qt (in case the Qt thread is stalled). Note
  that it is not possible to peek in qt X11 event queue from a non gui thread as
  the QX11Info::peekEventQueue is no longer thread safe since 5.12.

some compositor requires to set Qt Attributes before Qt application
is started such as selecting the right graphical backend (ie: dcomp needs to set
OpenGLES). And some compositor needs know wich QPA is in use (ie: x11 vs
wayland), this can only be known after QApp is started.

  this allows to unload the GUI part of the interface without destroying the
  windows that may still be used by the vout window part.

  This is a preparatory commit

  this way, qml files can be translated using vlc usual tools rather than
  qt own tools

So lua 5.2 compatibility declarations can be made in one place.

Lua is an important part of VLC and abusing misc has gone a bit too far...

(da big courmischage)

* commands/cmd_fullscreen.*, parser/interpreter.cpp: added a
  "vlc.fullscreen()" command

  win32, by ipkiss and myself...
 Among the features:
 - framework rewritten from scratch, heavily based on design patterns
  => new controls can be (hopefully) created more easily, portability
  to other OS is better, and the interface is less dependant from
  the vlc core
 - new concept of "layout", to provide a window with several different
  views (as in winamp3 skins)
 - controls can now be placed at a relative position to the edges of
  a window, which allow controls and layouts to be resizable (e.g
  for the playlist window)
 - Use of libpng and libfreetype2 for better portability between x11 and
   win32 => ttf fonts and antialiasing
 - New DTD for the xml theme ( *it will probably change again* )
 - Very very beginning of scripting in the xml file
 - And many things I miss
 - And probably many bugs ;)

                                 Dynamic device support.
  * ./modules/gui/macosx: Minor fixes and cosmetic changes.

    to be still crashing.

   As for video output 4, this breaks almost everything, but I'll slowly
  do what remains to be fixed during the weekend.

   Changes in vlc:
   ===============

  * vlc is now a very small program (20 lines) which uses the libvlc API;
   it is quite simple for the moment but can be extended in the future.

  * interfaces, decoders, video outputs, etc. are now almost the same
   objects (yes, I know, this is C++ redone in C) and are structured in
   a tree. More about this later, but basically it allows the following
   nice features:
    - several interfaces
    - several playlists with several outputs
    - input plugins spawning helper interfaces (will be used for DVD menus)
    - anything spawning anything; I swear there are useful uses for this!

  * libvlc can be used in other programs; I'm currently writing a Mozilla
   plugin for my employer.

   Things currently broken:
   ========================

  * most interfaces, most ports
  * the playlist handling (almost finished rewriting this though). This means
   no file can be played from the GUI, you need to use the commandline. This
   also means it segfaults at EOF, when exiting the program, and it sometimes
   refuses to open a file when asked to.

 * Added a win32 interface plugin, developed with Borland C++ Builder.
   To build the plugin, follow the instructions in INSTALL-win32.txt

 * Known bugs:
        - subtitles don't work
        - a crash occurs when the user exits by pressing 'q' in the vout
        - when moving the slider, position in the stream updates even if
          the slider isn't released yet

 * TODO list:
        - clean code in menu.cpp
        - adapt lool's enhancements of the Gtk+ preferences box
        - write drag-and-drop stuff
        - and of course, fix known bugs :)

 * For those of you who can't wait till the next release to test the win32
   interface, binary files are available here:
   http://www.via.ecp.fr/~ipkiss/intfwin/vlc.zip
   Enjoy!

  * Fixed compilation (and quite probably runtime) issues under IA64
    due to mixed int/void* casts.

  * DirectX enhancements by Gildas Bazin, such as software rendering.
  * Merged dvdcss_init and dvdcss_open into dvdcss_open, and dvdcss_close
    and dvdcss_end into dvdcss_close. libdvdcss API now has 7 functions.
  * Another failed attempt at profiling vlc under Linux: ported the
    threads API to GNU Pth. Activate with --enable-pth. It doesn't seem to
    spawn new threads for me, maybe someone will have better luck.
  * Makefile optimizations.
  * Automatic build of libdvdcss if not found.

title/chapter/audio/spu/angle, we tell the input to do intead of doing
it inside the interface. It results in fewer locks during the changes.

*The dvd plugin reads again blocks of 32 sectors to gain speed since
there are no more lock-ups during stream change. I've also created a new
file that contain function to described video and audio streams with ifo
datas.

The changes are made only for gtk. We should update the other interfaces
soon (beos at least).

There is a memory corruption somewhere that make the vlc crash. I've no
idea where to search.

*added a b_stopped flag to interface playlist to have a stop function in
interface plugins. As a consequence, the playlist no longer loops on end
but wait for the user to press 'play' or to add another item (gtk/gnome
interface). I think that other plugins are broken but it shouldn't be
difficult to repair: just add a 'p_main->p_playlist->b_stopped = 0' in
play functions and 'p_main->p_playlist->b_stopped = 1' when you have to
stop.

*Updated gtk interface so that it has the same features as gnome. I
think I will merge the code so that we don't have to copy and paste each
change. Only the .glade file would be different.

  * Fixed an aspect ratio issue in the SPU decoder, and optimized the
    SPU renderer.
