Only --addr implies announce-if-public: --bind-addr does not.
It's also possible to have --bind-addr to an automatic Tor address:
you'd have to dig the onion address out of the logs or getinfo to use
it, but it's possible.

This is a best effort attempt to skip connection attempts if we detect a broken
ISP resolver. A broken ISP resolver is a resolver that will replace NXDOMAIN
replies with a dummy response. This is best effort in that it'll only detect a
single fixed dummy reply, it'll check only on startup, and will not detect if we
switched networks. It should be good enough for most cases, and in the worst
case it will result in a connection attempt that does not complete.

Cut & paste means we sometimes sent NULL:

In this case, local and remote are *both* NULL; so if someone tries to
send a packet with take(), we need to free it.

I think this is what is causing #1536: getting disconnected causes gossipd to
attempt to reach the peer again, unconditionally setting the flag to tell the
master. At the same time the master also issues a reaching command (which is
allowed since it is its first), but then it clashes on the already set
flag. Setting this flag only when the master actually needs to be told should
fix this.

A failed compaction shouldn't be deadly, but we should also not attempt to do
one on every gossip message after the first one fails.

`gossip_store_add` is the entry point for messages from the network, so it
should do the bookkeeping and disable on failures. `gossip_store_append` is the
shared function that wraps messages and writes it to the given file. This is
shared between the from network path and the compaction path, so we don't
directly use the `gossip_store` instance, but `fd`s.

We write both when coming from outside, as well as when compacting, so we
extract the write functionality to use it in both cases.

This makes the exposed interface much smaller, cleaner and will allow us to just
replay gossip messages from the broadcast.

Two cases:
1. Node no longer has any public channels: remove node_announcement.
2. Node's node_announcement now preceeds all the channel_announcements:
move node_announcement to the end.

This lets detect if a node announce preceeds a channel announce once we
delete the node announcement.

We *accept* a node_announce if we have a channel_announce, but we
can't queue it until we queue the channel_announce, which we only do
once we have recieved a channel_update.

Since we currently only (ab)use it to send everything, we need a way to
generate boutique queries for testing.

We have a function called 'wake_pkt_out' which is really 'start
gossiping', so rename it to 'wake_gossip_out'.
In addition, it's fired both on a timer, and in response to our first
gossip_timestamp_filter, which leads to very confusing (though,
technically, not incorrect) behavior.
Keep a single timer at all times, which now doubles as the flag to
indicating we're syncing right now. Set it once we're done syncing
gossip.
Technically this means we got from once-every-60-seconds to
quiet-for-60-seconds-between-gossip, but that's OK.

And initialize filter (to "never") when we negotiated LOCAL_GOSSIP_QUERIES,
and send initial filter message.

This is kind of orthogonal to the other changes, but makes sense: if we
would instantly or never prune the message, don't accept it.
