We've been getting a bunch of 'warnings' about an unknown mark. This
silences the warning, by registering the mark as expected.

We tried to send an absurdly-long message, because our limit
was really large, as we were subtracting the tlv length, not
the tlv overhead.
In addition, we were treating the array as a tal object, which
it isn't if the offset is non-zero.

Actually, it's more complex to translate the xpub descriptor to
testnet because of the descriptor checksum.

This adds a command which outputs the two output descriptors
corresponding to our onchain wallet.
This can be useful for an external service to monitor / send fund to our
wallet.
Further, an "xpriv" version of such descriptors could be used to import
onchain funds on a new wallet.
Changelog-Added: lightning-hsmtool: a new command was added to hsmtool for dumping descriptors of the onchain wallet

tools: Add `generatehsm` method to hsmtool to derivate BIP32 seeds from a
mnemonic using the BIP39 standard.
The new method uses libwally for the BIP39 to BIP32 derivation. It also
fails if an hsm_secret file already exists, so we do not overwrite
someone else's wallet without noticing.
It allows the use of passphrases, the ECHO mode in the terminal is
disable for higher security.
It currently supports "en", "es", "fr", "it", "jp", "zhs", "zht".
Changelog-Added: hsmtool: `hsm_secret` generation from a seed-phrase following BIP39.
We used to create the entire reply, the if it was too big, split in
half and retry.
Now that the main network is larger, this always happens with a full
request, which is inefficient.
Instead, produce a reply assuming no compression, then compress as a
bonus. This is simpler and more efficient, at cost of sending more
packets.
I also renamed an internal dev var to make it clearer.

It's not (yet?) compulsory to have the timestamps, but handing them around
together makes sense (a missing timestamp has the same effect as a zero
timestamp).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The spec (since d4bafcb67dcf1e4de4d16224ea4de6b543ae73bf in March
2020) requires that reply_channel_range be in order (and all
implementations did this anyway).
But when I tried this, I found that LND doesn't (always) obey this,
since don't divide on block boundaries. So we have to loosen the
constraints here a little.
We got rid of the old LND compat handling though, since everyone should
now be upgraded (there are CVEs out for older LNDs).

Changelog-Removed: Support for receiving full gossip from ancient LND nodes.
We previously registered hooks up in who-replies-to-getmanifest-first
order, but then if any had dependencies it would scatter that order.
This allows users to manually set dependencies developers have
forgotten by specifying the plugins manually in their configuration or
cmdline. This was an excellent consideration by @mschmook.

Now both python and c libraries are updated, we can officially
deprecate the old form.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Deprecated: plugins: hooks should now be specified using objects, not raw names.
The next patch will use these to order the hooks.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: plugins: hooks can now specify that they must be called 'before' or 'after' other plugins.
This adds a `state_change` 'cause' to a channel.
A 'cause' is some initial 'reason' a channel was created or closed by:
/* Anything other than the reasons below. Should not happen. */
REASON_UNKNOWN,
/* Unconscious internal reasons, e.g. dev fail of a channel. */
REASON_LOCAL,
/* The operator or a plugin opened or closed a channel by intention. */
REASON_USER,
/* The remote closed or funded a channel with us by intention. */
REASON_REMOTE,
/* E.g. We need to close a channel because of bad signatures and such. */
REASON_PROTOCOL,
/* A channel was closed onchain, while we were offline. */
/* Note: This is very likely a conscious remote decision. */
REASON_ONCHAIN
If a 'cause' is known and a subsequent state change is made with
`REASON_UNKNOWN` the preceding cause will be used as reason, since a lot
(all `REASON_UNKNOWN`) state changes are a subsequent consequences of a prior
cause: local, user, remote, protocol or onchain.
Changelog-Added: Plugins: Channel closure resaon/cause to channel_state_changed notification
If a tx is larger than 2k, libwally will do an alloc:

test suite, and found no other places.

Just applied the same suppression as rusty in:
6635fe12e4 (Rusty Russell 2020-05-15 15:57:29 +0930 146)
/* cppcheck-suppress uninitvar - false positive on f1->bits */
My cppcheck was complaining about the same issue in the following functions.
I wonder why travis does not care though.
