Rusty Russell f6d22ed0cf configure: new script.
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.

Rusty Russell 76dd1577bd external: fix submodule handling for parallel builds, submodule URL changes.
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.

Rusty Russell da55d3c0ff gossipd: handle node_announcement when channel_announcement removed.
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.

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.

Rusty Russell db6a6442cb gossipd: single-thread the gossip timer.
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.

We use the same system as for gossip: we trickle out replies when we're
otherwise idle.

As we trickle out replies to query_short_channel_ids, we remember the
pubkeys of nodes we mention.  At the end, we sort and uniquify, and
then send any node_announcements we have for those.

When opening a number channels from a single node we could end up not waiting
for the funding tx to make it into the mempool, instead triggering on a previous
`sendrawtransaction` or `CHANNEL_NORMAL` in the logs. This now checks that the
actual funding transaction makes it into the mempool and that we wait for the
depth change for that specific channel.
