Antoine Poinsot 9f8e2e0502 tools: add a new 'dumponchaindescriptors' command to hsmtool
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

positiveblue 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.

Rusty Russell aa441e3b27 tools/generate-wire.py: fix loop logic for towire_xxx_array
We have to handle singletons which are arrays of variable-length entries:
this needs to be a ptr-to-ptr.

        u32 fee_proportional_millionths;

Rusty Russell 897c53ce1c tools/generate-wire.py: fix loop logic for towire_xxx_array
has_len_fields() doesn't cover our blacklist of variable types, so if
we have an array of them, this logic is wrong.  This happens in the
the bolt13 patch:

```C
struct tlv_offer_tlvs_blindedpath {
        struct pubkey blinding;
        struct onionmsg_path **path;
};
```

Before:
wire/gen_bolt13_tlv.c:
```C
		for (size_t i = 0; i < tal_count(r->blindedpath->path); i++)
		towire_onionmsg_path(&ptr, r->blindedpath->path + i);
```
After:
```C

		towire_onionmsg_path(&ptr, r->blindedpath->path[i]);

Rusty Russell 76813d6f90 tools/generate-wire.py: fix varsize assignment.
Code like this is suspicious:

	subtype_varsize_struct->field_0 = *fromwire_test_features(subtype_varsize_struct, cursor, plen);

In fact, it is a memory leak since we copy and don't free the fromwire
result.  Really, field_0 should be a pointer.

We don't hit this case (yet!) in spec-generated code, but I did for
bolt13.

Here's the difference in gen_test output:

joe.miyamoto 0b1f8fdbf0 Take LIGHTNINGD_NETWORK env variable in Dockerfile.
Before this, docker image will never detects that
`lightning-rpc` was created if it is running in regtest
or testnet, because the file will be created under
subfolder for each network name, and entrypoint does not
check "lightning-rpc" file in those folders.
By specifying `LIGHTNINGD_NETWORK` environment var
in dockerfile, we can now check correct path.

Changelog-Added: Docker build now includes `LIGHTNINGD_NETWORK` ENV variable which defaults to "bitcoin". An user can override this (e.g. by `-e` option in `docker run`) to run docker container in regtest or testnet or any valid argument to `--network`.

`struct tx_parts` is just a txid and a bunch of inputs and outputs,
some of which may be NULL.

This is both a nod towards a future where we (or our peer) can combine
HTLCs or (in an eltoo world) commitments, although for the moment all
our tx_parts will be complete.

It also matches our plan to split `bitcoin_tx` into two types: this
`struct tx_parts` where we don't know input amounts etc, and `psbt`
where we do.

Rusty Russell ae7485d2ac tools/generate-wire.py: don't define empty enums.
For bolt 13, we have no message types, just a TLV.

Rusty Russell b0c9059602 tools/generate-wire: no more lonely messages!
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward.  This changes it to directly
access those fields.

This is not only more elegant (60 fewer lines), it would also be
more cache friendly.  That's right: cache hot singles!

lisa neigut 9663d110d1 build: make non-parallel
There's a race condition with loading the submodules that's causes a
build failure on my machine, since the libwally 'includes' aren't on
disk yet when the gcc build step starts.

Rusty Russell 490a819402 lightningd: add `blinding` and `enctlv` field to `struct route_hop`.
This will be used when we want to specify these in a route.  But for now, they
only alter gossipd, which always sets them to NULL.

Rusty Russell 11c21f97a6 devtools/decodemsg: don't crash if we have multiple tlv options.
We call tal_count(msg) after we've moved msg, and that causes an abort.

Vasil Dimov 3ce0552dd4 build: use locale-independent sort for mocks
Use `LC_ALL=C sort` instead of `sort` so that mocks get sorted in
the same way on all developers' environments.

Re-record the result of `make update-mocks`.

Rusty Russell d9fc99ea39 channeld: simplify loading of pre-existing HTLCs.
We currently abuse the added_htlc and failed_htlc messages to tell channeld
about existing htlcs when it restarts.  It's clearer to have an explicit
'existing_htlc' type which contains all the information for this case.

Rusty Russell dd690553b8 channeld: handle onion messages.
