gossipd: track what peer gave us gossip msgs so we can credit it.

Browse Source 
Since we have to validate, there can be a delay (and peer might
vanish) between receiving the gossip and actually confirming it, hence
the use of softref.

We will use this information to check that the peers are making progress
as we start asking them for specific information.
