This URL format is handed out by youtube when a user uploads and
publishes a live stream through their account. This is just an alternate
URL format over the classic HTML page for a video. We already have live
stream support for these when applicable.

This will avoid ambiguity when adding encoder functions.

Note that the malloc() and indirection must be retained because
picture_NewFromResource() requires it.

UpnpInstanceWrapper::Callback() can be called while Upnp is unregistering via
UpnpUnRegisterClient(). Both functions locked the same mutex (s_lock) and this
resulted to a deadlock.

Add a new mutex to protect only the upnp callback.

pf_open from service_discovery shouldn't block but UpnpSearchAsync can take
more than one seconds. Indeed, contrary to what the libupnp doc states,
UpnpSearchAsync is blocking (select() and send() are called).

This is not a perfect solution. Indeed if pf_close is called just after
pf_open, it will also block.
