Sort the list  

Now we can legitimately not receive them, ahaha!

misc/events.c: We do want to send events to multiple listener. (oops, I should get some sleep). In this situation we can simply unlock for the time being making sure we won't reuse resources that can disappear.

control/media_discoverer.c: Implementation of a media_discoverer libvlc object based on top of services_discovery.

playlist/services_discovery.c: Improved services_discovery object, playlist independant. Now, the services_discovery plugin have to be converted to use this interface.

They should not be used by plugins. And in fact, they are not.

It's pretty useless to copy the same value to every single object.
