DO NOT MERGE - Make Ethernet more reliable.

1. If DHCP fails, set the score to 0. Coupled with changes in
   NetworkAgent, that will cause us to retry DHCP the next time
   the link is plugged in.
2. Send LinkProperties before sending NetworkInfo, because of
   a race in NetworkAgent.
3. Make Ethernet work properly after a runtime restart.
4. Improve locking.
5. Clarify how things work in comments.
