Rusty Russell afbddcf7f3 lightningd: fix crash on rapid reconnect.
Happens occasionally when running
`tests/test_connection.py::test_mutual_reconnect_race` (which is too
flaky to add, without more fixes):

Rusty Russell 3f98cf3fce lightningd: track weird CI crash in test_important_plugin
Looks like we woke one of the startup io_loops early, and thus
we thought we'd finished connectd_activate and we hadn't.  This
caused us to use an uninitialized ld->announceable array, and
finally caused an assert fail in the main loop.

Make *every* loop assert that it was exited for the correct reason,
so if it happens again, we can maybe figure out what part of
the code to look at.

```
lightningd: lightningd/lightningd.c:1186: main: Assertion `io_loop_ret == ld' failed.

Rusty Russell d2952576cd pyln-testing: restore proper streaming behaviour for lightningd.
Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it.  We could restore the thread we
were using before, but that added more problems than it solved.

This means that we need the hsm password prompts in the log though.

Rusty Russell 517828adb2 lightningd: don't print nasty message when onchaind fails partially-failed HTLC
1. We set an outgoing htlc's `failonion` when we get a commitment_signed.
2. We don't transfer it to the corresponding incoming HTLC until we send
   commitment_signed and receive revoke_and_ack (meaning, outgoing htlc is
   completely dead).
3. If between these steps we go onchain, onchaind (after 3 blocks) tells us
   to fail the HTLC.
4. hout->failonion is set, but hout->hin has not been failed yet.  We
   do a sanity check and print a nasty message, and fail it with
   WIRE_PERMANENT_CHANNEL_FAILURE instead of relaying the error.

So handle this case explicitly.

Rusty Russell 36a2491a89 json: fix up msat amounts in non-_msat fields.
We had json_add_amount_msat_only(), which was designed to be used to

However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
   xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
   the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
   interface, where "XXXsat".

lightning-cli plugin start - Assume default relative path
When starting a plugin, if the plugin path cannot be found in
absolute context, assume it is a relative path to the default
plugins dir. As a result, the following now works when my_plugin.py
is installed in the default plugins dir:

lightning-cli plugin start my_plugin.py

Also update the plugin documentation to reflect that the use of a
relative path is now available.

This adds config and commandline options for htlc_min_msat, htlc_max_msat and
announce_discovered_ip. The default is 0msat for htlc_min_msat, unlimited for
htlc_max_msat and enabled for announce_discovered_ip.

The announce_discovered_ip gets the disable commandline switch --disable-ip-discovery

Rusty Russell 2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

Rusty Russell 66e264d6b3 lightningd: new setchannel command.
Based on setchannelfee, but expanded to allow setting max htlc amount (and others
in future?).

The main differences:
1. It doesn't change values which are not specified (that would be hard to
   add fields to!)
2. It says exactly what all values are in any potentially changed channels.

Changelog-Added: JSON-RPC: new `setchannel` command generalizes `setchannelfee`.

Rusty Russell 65be18d355 memleak: handle libwally allocations better.
Things allocated by libwally all get the tal_name "wally_tal",
which cost me a few hours trying to find a leak.

In the case where we're making one of the allocations the parent
of the others (e.g. a wally_psbt), we can do better: supply a name
for the tal_wally_end().

So I add a new tal_wally_end_onto() which does the standard
tal_steal() trick, and also changes the (typechecked!) name.

Rusty Russell 4dc72dd829 dualopend: tell lightningd about new channel as soon as it's locked in.
Once we send funding_locked, gossipd could start seeing channel_updates
from the peer (which get sent so we can use the channel in routehints
even before it's announcable).

Rusty Russell e841e69b1b channeld: send channel updates and announcements via lightningd.
We're weaning per-peer daemons off having a direct gossipd connection.

Rusty Russell e8554c862a channeld: keep local copy of latest channel_update for errors.
Now we don't ask gossipd, but lightningd keeps channeld up-to-date.

Rusty Russell 5065bd6fc2 lightningd: use our cached channel_update for errors instead of asking gossipd.
We also no longer strip the type off: everyone handles both forms, and
Eclair doesn't strip (and it's easier!).

This way it can flush it if it was pending.

Rusty Russell 51d23ffcd3 gossipd: infrastructure to tell lightningd about local channel updates.
We want it to keep the latest, so it can make its own error msgs without
asking us.  This installs (but does not use!) the message handler.

Rusty Russell a8bed542f7 lightningd: start gossipd after channels are loaded.
This is in preparation for gossipd feeding us the latest channel_updates,
rather than having lightningd and channeld query gossipd when it wants
to send an onion error with an update included.

This means gossipd will start telling us the updates, so we need the
channels loaded first.
