dd59d0617d lightningd: expose last_stable_connection in RPC.
This isuseful to find completely dead channels which are worthy of
closing.

Changelog-Added: JSON-RPC: `listpeerchannels` field `last_stable_connection` showing when we last held an established channel for a minute or more.

95bc730894 lightningd: set last_stable_connection 1 minute after channel reestablished.
This is a nice reflection of channel stability: in particular, worse case
ping time is 45 seconds, so we should have had some traffic.

81a280d8a3 lightningd: expose reestablished field.
This is useful to see if we've really made progress, or just bounced
off the peer (e.g. it doesn't know the channel, or we have fallen
behind somehow).

Changelog-Added: JSON-RPC: `listpeerchannels` new field `reestablished` set once we've exchanged `channel_reestablish` messages.

40d063cda4 channeld: notify lightningd once we've exchanged reestablish messages.
In particular, we were sending `announcement_signatures` before
`channel_reestablish`; we allow this because LND used to do it, but
it's not spec compliant.

e4b21b467a lightningd: refine heuristics for remote address selection.
Rather than take the first two from peers with committed channels, use
the most common address given by at least 2 peers, and accept the majority
from non-committed peers if there are no committed peers.

This works well with the node_announcement rework, which waits until
everyone has a chance to connect before creating the node_announcement.

Mining 13 blocks to close the l1->l2 channel also causes the l2->l3

query the channel we want directly to make it more robust.
