Alessandro Decina 718837d914 osxvideosink: add code to optionally run the cocoa main runloop in a separate thread
Add a little hack to run the cocoa main runloop from a separate thread _when_
the main runloop is not being run (which means that the app doesn't use cocoa).
Runloops are thread specific, so the hack boils down to getting the runloop for
the main thread and setting it as the runloop for our dedicated thread.
