Also, make it clearer what is shared and instance-specific

So,
libvlc_t ==> libvlc_global_t
vlc_t ==> libvlc_int_t (internal instance)

p_object->p_libvlc ==> p_object->p_libvlc_globale
p_object->p_vlc ==> p_object->p_libvlc

VLC_OBJECT_VLC ==> VLC_OBJECT_LIBVLC

And by the way, there is some cleanup required :) (ie, some things are created in the global object instead of the instance-specific one)

* removed some further hangover from the original patch and finally added embeddedWindow to the xcode project

- basically written by Jerome Decoodt <djc at videolan dot org> aka DiDjCodt
plus
- various patches, coding-style fixes, etc. here and there
- integration to VLCControls
- automagic fading-in and -out when in fullscreen mode

TODO:
- get and use native graphics. These are currently being prepared by Simon Damkjaer Andersen, who already donated new playback mode icons (to be committed soon)
- implement the volume slider
- fix seeking with the time slider
- check for memory leaks
- further clean-up

ATTENTION:
for the moment, you need certain images from Jerome's patch to get this running. Put them to extras/MacOSX/Resources/ and it'll work. Otherwise, VLC won't crash, but only show strings.

* Patch from Basil Achermann to handle esc and space keyboard events in VLCControl when the controller is active
* It seems that corrects a bug when the controller was the acrtive window in fullscreen (that shouldn't happen, but well...)
* Best thing to do would be to handle the keypresses from the vout here too, I guess...

* Fix enabling of the step forward/backward functions

- accessible by double-clicking on the time-counters and through a menu-item in "Playback"
- the class of the time-counters is VLCTimeField now, because we need to fetch the mouseDown-event. There are no further changes compared to NSTextField.

* A few Mac OS X intf fixes. To be honest. we should rewrite the thing from scratch. it's a mess... 

* Embedded Vout should work now
* To create an embedded vout, just create a custom view of type VLCEmbeddedVoutView in interface builder
* Just make sure you define the view as resizeable
* Hotkeys and mose events should work
* Tests with the mozilla plugin are welcome

Merged OSD functionality on the same core functions. All OSD functionality is described in include/vlc_osd.h now, which entirely replace include/osd.h. The file src/video_output/video_widgets.c uses functionality from src/osd/osd_widgets.c now.

Added --volume-step to override AOUT_VOLUME_DEFAULT. This will give an OSD menu (or skins2) designer to freedom to decide how many steps he wants for turning up the volume from 0 to 1024. It is an advanced option so most users will never see it. Can someone check the MacOSX changes for this? I made them but cannot compiler and test it (I don't have a Mac).

(da big courmischage)

* Changed mute hotkey to command-alt-arrowdown (like in iTunes) to avoid dupe with messages window hotkey.
* Solved a deadlock due to volumeGet. Remember locking functions are not allowed from the GUI thread.
* Fix the OSD feedback of the Repeat One, Repeat All commands
* Added Chris Clepper to the THANKS file for his OpenGL fix [11368]

  main thread (one more step to hopefully fix #45)
 macosx/controls.m: fixed a tiny memleak

* vcdx/vcdplayer.c: disabled l10n of various error messages
* vcdx/vcd.c: disabled l10n of 2 debug masks. They are horribly to translate and used by advanced users only, who should speak English well enough for this purpose
* rest: disabled l10n of various strings or debug masks which cannot be translated

more to come

Update the info displayed in the playlist when you change the play mode in the menu (had this ever worked ?)

* different way to remember fullscreen state.
* update the playlist on item-append and item-deleted calls.
* fixed video-on-top with opengl vouts on OSX.

Apparently menu's got smarter in Tiger. As a workaround for the old version, you should first open the Help menu and then drag to the other menu's.

This still isn't the correct way to fix it. We should attach a callback function to the autogenerated menu's and have the callback function update the menu. (but this will work for now).

* controls.h: removed "o_open"
* intf.*, open.*: make sure the open-nib is loaded only once, don't load it at launch time but dynamic and do it in VLCMain, so VLCOpen does not know about it anymore
* MainMenu.nib: we don't need instances of VLCOpen and VLCOutput anymore

* src/video_output/vout_intf.c: use above option and set the default destination for snapshots
   on OS X to the Desktop.
* REST: Add the Snapshot command to the menu's etc.

* It enabled even when no vout is present
* Still a little issue with the fullscreen hotkey

  + vout.m contains the common code for the QT video output and the
    GL provider (window creation, events handling)
  + opengl.c: higher priority on OS X
 Things are a bit broken atm, any help to debug is welcome ;p

  Testing would be welcomed very much.

  - The VLCApplication is now launched at the vlc.c level instead of at the module level. Allows VLC to be a more valid Mac application, also removes the vout intf dependancy (use ncurses to disp. video :).
    This wasn't done at the libvlc level, because a mozilla plugin would no longer be able to function properly.
  - Some functionality of the macosx vout may not work without the OS X GUI, and not all of this is checked yet.
  - There is a symlink in VLC.app/Contents/Mac called clivlc that will force it back to a fullblown cli app when you want, so it can still be run by a user who isn't logged in via GUI.
  - there are some autorelease leaks which need to be tackled.
  - moved a lot of the VLCApplication func. to the VLCMain class.
  - VLCMain is a +sharedInstance now.
  - the complete OS X interface is still badly broken because of the many API changes lately. any volunteers?

Examples:
VLC.app/Contents/MacOS/VLC [-I macosx]
launches VLC as before (requires you to be logged in via GUI)

VLC.app/Contents/MacOS/VLC -I ncurses
launch vlc with a ncurses intf and display video on your mac
(requires you to be logged in via GUI)

VLC.app/Contents/MacOS/clivlc -I telnet -d
launch vlm remotely trough ssh in daemon mode, on a GUI'less server for instance, and stream your vids

Now how is that for combining GUI and cli in one application on the mac?!!? :)
jlj? I finally understand now how the OS X interface works !

When you want to use OSD, you have to register an OSD channel, by calling
vout_RegisterOSDChannel, then pass it to vout_CreateSubPicture.
There is a particular channel, DEFAULT_CHANNEL that can be used for
general purpose.
See modules/control/hotkeys.c for an example.

* added i_channel and i_content properties to subpicture_t
* p_last_osd_message is no more used

An OSD channel can contain simultaneously an OSD text and an OSD widget.

* modules/gui/macosx/controls.m: fix the autogenerated menu.
