Mike Frysinger e8a761519b sim: dv-sockser: pass up connected state
A few ports rely on internal dv-sockser state in order to detect whether
a connection has been made (look for 'extern sockser_addr').  Rather than
continuing that tradition, extend the existing status function to return
the socket connection status.
