Use an vlc_object_t destructor.
Don't use free, instead of vlc_object_release().

Now "#include <vlc/vlc.h>" defines all the definitions needed to use libvlc_*.

* New layout is the following:
vlc/common.h: Global definitions
vlc/deprecated.h: Deprecated stuff
vlc/libvlc_structures.h: Contains all libvlc_* structures.
vlc/libvlc_events.h: Contains libvlc_event_t structure.
vlc/libvlc.h: Contains all libvlc_* functions
vlc/libvlc_media_list.h: Contains all libvlc_media_list_* functions
vlc/libvlc_vlm.h: Contains all libvlc_vlm_* functions.
vlc/vlc.h: Use this header to use libvlc-control.dylib.

Some MP4-knowledgeable dev (fenrir?) really should check that this is
not too restrictive a check.

Note: This is completly crippled and can easily lead to some race condition. We need to re-think the whole modules to avoid those.

This avoids the circular dependency there is from playlist and input item, which creates a dead lock at exit.

macosx: Attempt to avoid a crash. Note that this can't be working properly and could create a rare race.

objects: Allow certain operations when the object refcount is zero (read, allow certain operations from the object destructor), and make sure we don't return objects that are being destroyed.

This sanitize the circular dependency there is between playlist and input and allow a safe destruction.
