`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.

This way the object file correctly depends on external headers. Currently
a parallel build on a clean tree can give:
```

Make should only run configure if config.var already exists:
$ make
./configure --reconfigure
./configure: 65: .: config.vars: not found
./configure --reconfigure
./configure: 65: .: config.vars: not found
Makefile:179: recipe for target 'ccan/config.h' failed
make: *** [ccan/config.h] Error 2
You can use environment variables or the commandline to set defaults.
It looks very autoconf, but you don't need to learn m4.
Doesn't cover all the obscure flags, but it's easy to extend.

If we change an upstream URL, all submodules break. Users would need
to run 'git submodule sync'. Note that the libbacktrace fix was merged
upstream so this is no longer necessary, but it's good for future changes.
Also, stress-testing reveals that git submodule fails locking
'.git/config' when run in paralell. It also segfaults and other
problems.
This is my final attempt to fix submodules; I've wasted far too many
days on obscure problems it creates: I've already lost one copy of my
repo to apparently unfixable submodule preoblems. The next "fix" will
be to simply import the source code so it works properly.

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.

The modern, pytest based, tests now clean up after themselves by removing
directories of successful tests and the base directory if there was no failure.

Compares the `blocknum` in the `short_channel_id` with the range of blocks we
store in the database and abort if we should have known about it. Avoids
bombarding `bitcoind` with requests for channels that have already been spent or
were invalid in the first place.

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.

Previous replies weren't large enough; add another channel and then
use IO tracing to make sure the reply is zlib encoded.

Since we currently only (ab)use it to send everything, we need a way to

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.
