Rusty Russell a3696f0469 gossipd: allow faster updating, 2 per day, before ratelimiting.
This limit applies to both node_announcements (which we now send 1 per
day), and channel_updates; I've had reports of LND nodes going down
daily for database compation, so they end up ratelimited.

Changelog-Protocol: We now allow two channel_updates or node_announcements per day, up from 1.

Rusty Russell 93c00cc07d gossipd: force a fresh node_announcement every 24 hours.
Even if nothing has changed.  Note that this is different from simply
re-xmitting the old one, in that it has a different timestamp, so others
will re-xmit it too.

This is a side-effect of reports that node_announcement propagation
through the network is poor:

Rusty Russell d991f13516 gossipd: make sure we set the `urgent` bit if we move our own node_announcement.
node_announcement has to follow at least one channel_announcement.
When channels close, if this isn't the case, we remove the old
node_announcement and put it at the end of the gossip_store.

But we lose the "send even if they don't want it" bit in the case it's
our own node_announceent, so keep it.

This only happens if you don't change your node configuration at all
since you opened your first channel, but still worth fixing.

We expose the force_node_announce_rexmit() for later use.

Rusty Russell 0aad222c2d gossipd: rewrite update generation, remove local_chan.
local_chan was mainly around so we could "soft" disable channels (and
really disable them once we used the channel_update in an error
message).

Instead we introduce the idea of a "deferred_update": it's either
deferred indefinitely (a peer goes offline, if we need to send it in
an error we'll apply it immediatly), or simply delayed to avoid
spamming everyone.

The resulting rewrite is much clearer, IMHO.

Rusty Russell e7b263304e lightningd: Send updated onion spec messages.
It's very similar to the previous, but there are a few changes:

1. The enctlv fields are numbered differently.
2. The message itself is a different number.

The onionmsg_path type is the same, however, so we keep that constant
at least.

We renamed the enctlv field to encrypted_recipient_data in the spec, and the

Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.
