when using set_text on an image widget, vlc crashes
(trying to unlock when no lock is held)

Recent change in core(audio) now requires playlist to be passed as object
so that findAout can success (based on "find-input-callback" inheritance)

This is needed to protect the Xlib internal state. Xlib may still be
used by user interface thread, the GLX video output thread(s) and
PulseAudio -audio thread- while it initializes.

Fortunately, we do not need to lock X11 displays as every thread uses
its own. Hopefully Xlib is not buggy in that respect, but I am not so
sure :(

This should fix LP #419915.

This reverts commit 3dd62c35.

Suppress VLC media player <version> message if --quiet is passed as
first argument. Feel free to revert if this is an issue.

This fixes opening files with non-UTF8 sequences in their path (as long
as the file:// URI is %-encoded correctly).

As already stated (I think), this might be wrong. I have no clue what
codeset this file format is supposed to use.

Dynamically allocate the dir list to prevent potential array overflows (I believe that we were writing to the 5th element of a 4 element array since the luac commits).
