libvlc: intf-show and intf-popmenu must be created before interfaces are launched (via use of --extraintf)

This fixes 'vlc -I rc --extraintf skins' that fails to add a callback to these
variables because they are not yet created
(pointed out by assert failed in debug mode when calling var_DelCallback)

Singleton pattern is about not carring about this.

fmt.p_extra should only reference malloc'ed memory, since it is cleaned
with free() in es_format_Clean.

This patch reuses the same logic for p_vids as that of p_auds.

Instead it shows a "..." button which opens a menu with those locations.
Current location is thus always displayed as wide as possible.

This reverts commit c8a67b80.

freebox luasd is doing a wonderful job now.

The current contrib bin for i386 seems to be a bit broken here and most modules are x86_64 only.

Patch probably from arekm -- pld-linux . org

It doesn't work...

Thanks to DiDjCodt.

lua version doesn't support adding subitems and passing the option over to subitems.
One day the lua libs will be ready to offer feature parity for luafreebox and
this one will be able to go away. But not yet.

You can now load them with --services-discovery=freebox,frenchtv.
However non registered lua sd will still require --lua-sd=<name>.

This fixes the build on Mac OS X. This is probably not the best way
for non-contrib dependant build, but I don't have any better idea.
Feel free to make it works differently.

fix the un-premultiplying post processing step, which would yield values above 255 for full white - and thus shade some text.

So that debian packaging can take it.

Previously we were just saving the loaded modules which resulted in zero modules being saved to disk.
