This reverts commit 29847260.
I'd rather have a stable lua api (besides, vlclua_gettext is already a noop).

This fullscreen controller is copied from the main window.
It can be activated in fullscreen mode either via the 'i' hotkey
 or mouse middle button.

This patch ensures we get the same behavior on Vista/Win7
 (new vout_display) as we get on WinXP (old vout output with directx)

Opacity used to work only on newly loaded skins, but failed to work from
skins restored from a previous session.

This fixes vlc hanging when closed via the popupmenu in the taskbar.

Anyway:
 * cmml samples can't be found in the nature
 * cmml demux does not works AFAIK
 * we will remove cmml soon.

This patch opts for the new vout_window_SetFullscreen when a vout window
provider is available and keeps on the old way otherwise

macosx_dialog_provider: Don't waste a thread for nothing and make sure we call AppKit from main thread.
