50f8da85ac gossipd: fix response for large replies.
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.

This adds a command which outputs the two output descriptors

fa1483a00d hsm_secret generation from a seed-phrase
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.

9a575a98a0 gossipd: simplify large reply code.
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.

59f23bf23c gossipd: use straight counter instead of bitmap for query_channel_range replies.
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).

fb295ffb51 plugin: sort topological candidates by specified order.
We previously registered hooks up in who-replies-to-getmanifest-first

forgotten by specifying the plugins manually in their configuration or

8a8dabaa58 feat: adds state change cause and message
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.
