3b622f06c3 lightningd: use param_check on all commands which do extra checks.
This makes `check` much more thorough, and useful.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `check` now does much more checking on every command (not just basic parameter types).

eeee5d6249 lightningd: really fill in our own details when channeld says to make channel_update.
Now we've asserted that channeld would tell lightningd the same thing it
would do anyway, we can simply have channeld say "enable=True|False" and
lightningd fill in the other fields.

This means there's a pile of things channeld doesn't need to know any more!

9c04d0b02d lightningd: make sure that channeld_local_channel_update fields are redundant.
channeld used to talk directly to gossipd, so it made sense for it to
tell gossipd directly when it wanted it to make a new channel_update.

When that changed with v0.11, we simply directed the message via
lightningd.

But much of the information is actually told to channeld by lightningd!

So I applied this assertion and ran the test suite, before the next patch makes it redundant.

We got one assertion: test_setchannel_zero deliberately drives the
advertized htlc_max over the real htlc max in test_setchannel_zero for
testing.

4b4937b9bd gossipd: tell lightningd about all our previous channel_updates at startup.
This will at least *help* the case where these were not populated, causing us
to send errors without channel_updated appended.

It's not perfect: we can still send such errors if the gossip store is
corrupted, and we still send them for private channels, but it should
help.

(The much better fix is far more invasive, so slips to next release!)

7b9f1b72c6 lightningd: don't print zero blockheight while we're syncing.
In v0.11 (71f736678f) we changed lightningd to wait for gossipd to
acknowledge blocks before updating blockheight: this resolved a problem
which lnprototest had where it wanted to know when we'd fully digested
a block.

However, it broke the syncing case: until then we don't even tell
gossipd, so this stayed at zero.  We should use the current blockheight
for that corner case!

Fixes: #5894
Changelog-Fixed: JSON-RPC: `getinfo` `blockheight` no longer sits on 0 while we sync with bitcoind the first time.

532544ce4f gossipd: rename remote_addr to discovered_ip within gossipd
This is cleaner because, the `remote_addr` and `discovered_ip` are
related but two different things.

Within connectd and lightningd we use the peers `remote_addr` feature
to validate (and guess a port) to be used for IP discovery.

Also when a peer reports us a `remote_addr`, this is given to the plugin API
via the `peer_connected` hook. The network port here is not modified for
godd reason! This can be used i.e. to detect if we are behind a NAT.

But once lightningd figures enough peers report the same `remote_addr`,
it sets the port to the selected network and tells gossipd to use that for
`node_announcement` updates.

Hence, within gossipd, there is no (should not be) `remote_addr`.

Changelog-None

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.
