libvlc: In order not to be confused by a vlm created elsewhere, use a libvlc instance variable to old the vlm libvlc created if --vlm-conf was specified.

This also make sure the vlm created when --vlm-conf is specified gets really destroyed. Because find_object yields vlm and is never released.

libvlc: Don't use input_ItemClean. Anyway when we leak an object there is no use to delete it in the end. The mistake has already been done.

vlm: Only use gc enabled input item. (input_ItemClean and input_ItemInit shouldn't be used directly).

Instantiate VLM if vlm-conf option is used. You can now use VLM without having to launch the telnet or http interface.

We do maintain a lock around vlc_object_alive() because we want to make sure we won't miss the point when a concurrent thread will call vlc_object_kill(), that is set b_die and vlc_object_signal(). If we missed b_die and the signal, next vlc_object_wait() will dead lock.

We can't do what is advised in the documentation of vlc_object_alive(), but we try to stay close enough of it.

Remove useless variable

The whole point of a global lock is that it is... global. Destroying it
every time it's released is severe brain damage, as we end up taking a
different lock all the time (or worse destroying the lock while another
threads is competing for it).

We should really keep the global "libvlc" lock while initializing the
modules bank. Otherwise, if a second instance is created while the
first one is initializing, it may get an incomplete bank. This commit
addresses the problem w.r.t. the "main" module - only.

libvlc: rename libvlc_media_descriptor to libvlc_media and libvlc_media_instance to libvlc_media_player.
