The M1 Macs support both x86_64 and arm64 architectures, which forced
homebrew to use a different path for its storage (`/opt/homebrew/`
instead of `/usr/local`). If we don't adjust the path we'd mix x86_64
and arm64 libraries which can lead to weird compiler and linker
errors.
This patch just introduces `CPATH` and `LIBRARY_PATH` as suggested by
the homebrew team, and detects the current architecture automatically.
Changelog-Added: macos: Added m1 architecture support for macos
The extra entry in opt_table would never be called, leaving plugins
clueless why options keep defaulting.
Note that option registration outside startup does nothing.
Instead, dynamic plugins can use `plugin start [second_parameter]` to pass options.
Otherwise we hangs forever in startup when it was the last plugin, we would
miss destroy_plugin --> check_plugins_manifests --> io_break
e.g. when a plugin tries to register a bool option with a string as default value.
We noticed bogus behavior where (with 200 blocks added at once)
lightningd didn't see a DF channel open: this is because we told
lightningd about the new blocks (and it timed out channel) before
the watches for the transaction are fired.

We had this assertion fail, and I can't see a clear reason why. Remove it
(i.e. don't crash because we're having trouble with creating invoice routehints)
and add logging.
```

There are several possible causes for this:
1. We have two channels with the same rr_number. A quick audit shows we always set that rr_number to a unique value (and 64 bits, so wrap is not possible between the release and now!).
2. It's theoretically possible that sort() could compare a value with itself, but that would be really dumb: it doesn't that I've ever seen, but then, we've never seen this assert() hit, either.
3. listincoming has given us the same channel twice. I don't see how that is possible: we had a race where channels could momentarily vanish, but never be duplicated (emailed crash.log shows no duplicates!).
4. General corruption/freed memory access. If a channel we've just looked up is gone but still in the hash table, this is possible but would cause lots of random behavior and crashes.

Got complaints about us hanging up on some nodes because they don't respond
to pings in a timely manner (e.g. ACINQ?), but that turned out to be something
else.
Nonetheless, we've had reports in the past of LND badly prioritizing gossip
traffic, and thus important messages can get queued behind gossip dumps!

Because we expire cache every flush, in DEVELOPER mode that can happen in
just over a second. If gossipd takes a while to process the gossip,
this can mean we actually forget we received it from the peer.
Easiest fix is to run this test in non-DEVELOPER mode.
``` # With DEVELOPER, this is long enough for gossip flush.

If we can't broadcast the tx, confirm that it didn't end up in the

Check funding_outnum validity first to avoid reading invalid outputs
Changelog-Fixed: Fixed a potential issue if the number of outputs decreases in a dualopen RBF or splice.
This grows the routing state in order to index both okay-to-broadcast
and rate-limited gossip. The gossip_store also logs the rate-limited
gossip if useful. This allows the broadcast of the last non-rate-limited
gossip.
routing.c now flags rate-limited gossip as it enters the gossip_store but
makes use of it in updating the routing graph. Flagged gossip is not
rebroadcast to gossip peers.
Changelog-Changed: gossipd: now accepts spam gossip, but squelches it for
peers.
This will be used to decouple internal use of gossip from what is
passed to gossip peers. Updates GOSSIP_STORE_VERION to 10.
Changelog-Changed: gossip_store updated to version 10.
I had to parse quite a few of these files debugging zeroconf, so I
thought it might be nice to have direct access here.
Changelog-Added: pyln-testing: Added utilities to read and parse `gossip_store` file for nodes.
With zeroconf we have to duplicate the `local_channel_announcement`
since we locally announce the aliased version, and then on the first
confirmation we also add the funding scid version.
We used to agree up on the `minimum_depth` with the peer, thus when
they told us that the funding locked we'd be sure we either have a
scid or we'd trigger the state transition when we do. However if we
had a scid, and we got a funding_locked we'd trust them not to have
sent it early. Now we explicitly track the depth in the channel while
waiting for the funding to confirm.
Changelog-Fixed: channeld: Enforce our own `minimum_depth` beyond just confirming
The spec explicitly asks for the first point, while we were using the
most recent one. This worked fine before zeroconf, but with zeroconf
it can happen.
Not only can the outgoing edge be a zeroconf channel, it can also be
the incoming channel. So we revert to the usual trick of using the
local alias if the short_channel_id isn't known yet.
We use the LOCAL alias instead of the REMOTE alias even though the
sender likely used the REMOTE alias to refer to the channel. This is
because we control the LOCAL alias, and we keep it stable during the
lifetime of the channel, whereas the REMOTE one could change or not be
there yet.
