This reverts commit 68bcb6a4.

As pointed by courmisch, this is crashy.

Conflicts:

	src/vlc.c

Note: I don't think we did yet match the old behaviour, if we hit ctrl-c while in libvlc_new(), vlc isn't killed properly.

...if the destructor destroys them properly.

We need to do stuff BEFORE the playlist is destroyed

This will postpone a due abort or turn a crash into an abort.
Objects must not have children when they are destroyed per the current
design, though this seems to be a questionable choice.

(Code re-use rules)

The kept sout needs to be attached to the playlist, else we will
try to destroy vlm's souts before it's time to.
