This improves readability a lot and prevent us from reinventing the wheel.

Missing some cases that I could not test.
Also ffmpeg/chroma.c is locked, so I can but leave it broken.
Fix is for the remaining modules is obvious and the issue is easy to detect.

iso -> utf8, what's the problem of german people with strange, non ASCII, characters in their name ? --Rafaël Carré
Another patch by funman.

* Move out Advanced/Misc/Misc options
* Don't show any Stuff/General category anymore
* For interfaces, split out "General" from main interface settings
* Remove dummy from prefs
* Clean hotkeys settings

(Closes:#598)

(da big courmischage)

 beos/*: use B_KEY_DOWN/B_KEY_UP messages instead of KeyDown()/KeyUp()
   so we can have access to the key code and be more reliable (fixes a
   bunch of hotkeys). Fixed snapshots (missing pf_control)

* Each module can declare a "human-readable short name" with set_name
* Modules are sorted by category (set_category, set_subcategory).
  Modules configs can be separated by set_section()
* Separated audio-filter and audio-visual
* Separated extraintf and control
* New command and widget : add_module_list() for comma-separated modules
* Vfilters now use "," as separator

Do "50%","100%", ... need translation ?

They are currently translated, I did not touch this

   String choices lists can now also have a list of text descriptions associated with them.
   Added integer choices lists.
* modules/gui/wxwindows/: modified config widgets to use the new config options.
* ALL: updated for the new config options.

* modules/*: got rid of empty module objects.
* modules/gui/wxwindows/preferences.cpp: fixed the config options display for submodules.

                     screenshots...)

          It is not complete yet (see the TODO in PreferencesWindow.cpp)

* modules/*: sanitization of the modules description strings.

indicate wether it is an "advanced" option or not. The goal with this is to
hide the user from all the strange options that very seldom needs to be
changed. added an extra argument to all the add_* macros to indicate wether
the item is advanced or not.
* src/libvlc.h: added an "show advanced options" config option default
disabled
* src/libvlc.c: the advanced options are not listed by vlc --help and
friends unless --advanced is used
* modules/gtk/preferences.c: the gtk/gnome preferences dialog don't show
advanced options unless advanced is set
all: set the advanced flag to VLC_FALSE or VLC_TRUE for all options, by
using some common sense. Please check and correct

note: All interfaces should still work like they used to, see the change in
modules/gtk/preferences.c to find out how to "hide" options.

second note: I think I've changed all the modules, but I could not test
everyone for compilation, expect some broken modules (the fix is to add ",
VLC_TRUE" as last argument to the add_* I forgot)

modules/gui/beos/PreferenceWindow.h/.cpp

	- added settings for screenshot path and image format

	- removed "Save" button, added "Cancel" and "Revert" buttons

	- added revert functionality

	- changed class design for cleaner functionality,
		separated ApplyChanges() into more functions
		to have finer control

	- added more error checking and fixed memory leaks
		(config_GetPsz() returns char*, not const char*!)

	- all settings are now correctly saved and restored

	- some more cosmetic changes


modules/gui/beos/InterfaceWindow.h/.cpp

	- updated vlc way of saving settings to be on par with BeOS way
		and made it selectable in the code which way is used.
		However, the VideoSettings are still only savable in
		the BeOS way.

	- if dvd menus are used, the navigation menu enables a
		"Goto Menu" item. Unfortunately, I don't see a clean
		way to really detect the usage of dvd/dvdold in the
		currently playing stream. I wouldn't want to see
		if a playlist item has "dvd:" or "dvdold:" prepended
		at each interface update.

 * fixed an interface bug when launching a file from the command line
 * minor fixes or enhancements

Playlist is yet broken (maybe others things too)

    waveout, directx, qnx, beos, win32, macosx, and the AltiVec modules.
  * ALL: removed mention of AC3 in favour of A52.
  * ./configure.in, ./Makefile*: modules can now be built deeper than 1
    directory. As a consequence, the build is even slower (but I'm fixing
    this) and make clean doesn't work anymore.

    about 2000 lines of code.

    I could not test everything on every architecture, so please report
    any module breakage (especially on BeOS, OSX and QNX).

   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.

  * ALL: internationalized all configuration strings.
  * ./src/interface/main.c: we now set LC_CTYPE to get the right charset.
  * ./src/misc/configuration.c: lots of simplifications in the code.
  * ./po/vlc/pot: updated translations.

This is the first part of the new configuration architecture for vlc.
Two other parts will follow soon:
- config file implementation
- gtk configuration interface.

This part won't change much for end-users as these changes are mostly
internal, you will however notice that the command line interface has
changed. It will maybe be less user-friendly as I almost removed the
short options but it shouldn't a big problem when the config file is
implemented.

What as changed is that it is really easy now to add configuration
options to vlc. Plugins can also implement configuration options. All
you have to do is to declare a MODULE_CONFIG section in your plugin.
If you want to know more about this look at configuration.h and for some
example: main.c, dsp.c or xvideo.c

It would be nice if every developper could now start using configuration
options in there plugins and also enhance old plugins.

That's it, now let's hope I didn't break too many things ;-)

  * ./src/audio_output/aout_s16.c: fixed a segfault. It may have unexpected
    side effects because I don't know this part of the code, but at least
    it doesn't crash anymore.
  * ./plugins/beos/beos.cpp: first attempt at porting the BeOS plugin to the
    new video output and module systems. Doesn't work nor even compile yet.
  * ./configure.in: we now check the gtk-config version.

Some heavy changes today:
  * Removed duplicate function checks from configure.in.
  * Added extra magic to Makefile.modules so that the module Makefiles
    are now ridiculously simple. And I mean *simple*. Check it! This will
    make a possible switch to full autoconf/automake a lot easier.
  * Added the vlc version name to the plugin symbols, to be sure we only load
    plugins with the same version number. A nasty consequence is that you
    need to rebuild your tree after midnight if you are using a CVS tree :-)
  * Got rid of modules_export.h by #defining exported functions in the same
    header as their prototype.
  * Added modules_inner.h and other commonly used .h files to common.h so
    there are less and less files to include, and renamed common.h to
    <videolan/vlc.h>.
  * First modifications to the module handling system towards my ultimate
    goal to get rid of the *_Probe functions. Got rid of TestMethod and
    TestCPU, as well as src/misc/tests.c.
  * Wrote the chroma plugin handling functions. No YUV functions have been
    ported yet because it'ls a lot of work, but the core system works, I
    tried it with a naive yv12->rgb16 plugin (which will disappear when the
    real functions are ready).
  * Made a lot of functions in dvd_summary.c one-liners to avoid wasting
    too many output lines.
  * Fixed a segfault in input_dvd.c:DVDInit.
  * Added a fixfiles.sh script in plugins/gtk to be run after Glade has
    generated its C files.
  * Did some work on the KDE interface to make it suck a bit less. It still
    segfaults, but at least it runs and it looks less ugly.
  * RGB SDL rendering works again, though in 16bpp only.
  * Made plugins/vcd/linux_cdrom_tools.c independent of any vlc structure
    so that it'll be easily put in a library. Maybe libdvdcss?
  * Fixed VCD date display.
  * Merged vout_xvideo.c, vout_x11.c and vout_common.c into xcommon.c.
  * Wrote non-Shm XVideo output.
  * Made X11 output work again. Still pretty unstable, only works for 16bpp.
  * Additional french translation in po/fr.po. Any taker for the rest?
  * Fixed a segfault in video_output.c when the allocated pictures were
    not direct buffers.
  * If $DISPLAY isn't set, don't try to run the Gtk+ interface.
  * Replaced 48x48 .xpm images with 32x32 ones to conform to Debian policy
    (Closes Debian bug #126939).
  * Removed the automatic ./configure launch when running `make all' for
    the first time.

Stuff currently more broken than it ought to be:
  * The wall filter. Being fixed.
  * x11 and sdl plugins for depth != 16bpp.
  * Software YUV.
  * gvlc, gnome-vlc, kvlc shortcuts. Use --intf instead for the moment.
