Add more generic export-spa example

Browse source 
Replace the v4l2 example with a more generic version that can add
any spa node to a remote graph
Make the dictionary items const
Add some info to nodes and factories. Add the node info to the node
properties. We can then set the media.class directly on the node,
instead of letting the monitor set it.
Debug node info in spa-inspect.
Do async operation on the audiotestsrc and videotestsrc differently.
