gst-node-factory: node factory for GstSource nodes

Browse source 
The GstNodeFactory creates GstSource nodes without ports. When an
output port is created later, the proper GStreamer element will be
created in the node.

main.c registers a GstNodeFactory in the daemon, so clients can use it
in calls to CreateNode and CreatePort.
