1513a2d07e hsmtool: input encryption password from stdin
This slightly breaks the API, but still accept the input: we just don't
take it into account anymore.

For `dumponchaindescriptors`, we have to still take the old place of the
`network` parameter into account to not entirely break the API.

Changelog-Added: hsmtool: password must now be entered on stdin. Password passed on the command line are discarded.

ff8830876d wire/tlvstream: add tlv_make_fields helper to populate ->fields array.
This is vital for calculating merkle trees; I previously used
towire+fromwire to get this!

Requires generation change so we can magic the ARRAY_SIZE var (the C
pre-processor can't uppercase things).

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.

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.

aa441e3b27 tools/generate-wire.py: fix loop logic for towire_xxx_array

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:

        struct pubkey blinding;
        struct onionmsg_path **path;

Before:

```C
		for (size_t i = 0; i < tal_count(r->blindedpath->path); i++)
		towire_onionmsg_path(&ptr, r->blindedpath->path + i);

After:

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:

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`.

dafaf854c5 bitcoin/tx_parts: infrastructure for partial bitcoin txs.
`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.

When we have only a single member in a TLV (e.g. an optional u64),

This is not only more elegant (60 fewer lines), it would also be

89ceb273f5 wire: remove towire_double()
Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.

Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.

* Introduce a new param_millionths() that expects a floating-point
  number and returns it multipled by 1000000 as an integer.

* Replace param_double() and param_percent() with param_millionths()

* Previously the riskfactor would be allowed to be negative, which must
  have been unintentional. This patch changes that to require a
  non-negative number.

55173a56b7 Use dedicated type for error codes
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.

To resolve this:

* Introduce an error code type with a known size:
  `typedef s32 errcode_t`.

* Change all error code macros to constants of type `errcode_t`.
  Constants also play better with gdb - it would visualize the name of
  the constant instead of the numeric value.

* Change all functions that take error codes to take the new type
  `errcode_t` instead of `int`.

* Introduce towire / fromwire functions to send / receive the newly added
  type `errcode_t` and use it instead of `towire_int()`.

In addition:

* Remove the now unneeded `towire_int()`.

* Replace a hardcoded error code `-2` with a new constant
  `INVOICE_EXPIRED_DURING_WAIT` (903).

Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

2d45b13088 hsmtool: Make the backup copy in the same directory as the original
TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.

This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.

b2c4d5e952 build: fix developer mode compilation on FreeBSD
Recent FreeBSD versions use LLVM's lld as a linker, not the GNU ld.
Their behavior slightly differs, so adapt the build system to handle
either one.

* The LLVM's linker prints "undefined symbol:" instead of
  "undefined reference to". Tweak tools/mockup.sh to also look for that
  message.

* The LLVM's linker may only print the first dozen errors (omitting
  the rest to avoid flooding the screen). tools/update-mocks.sh relies
  on getting all errors as it extracts the missing symbols' names from
  the error output and creates mocks for them. Detect if errors were
  omitted and re-run, telling the linker to not omit any. The GNU linker
  does not support -error-limit=0, so unfortunately we can't just run
  with that option unconditionally from the first attempt.

* Nit: FreeBSD's sed(1) prints "t" for "\t" instead of a horizontal tab.
  Use a verbatim tab in the command, instead of "\t" which works on
  both.

Changelog-Fixed: Developer mode compilation on FreeBSD.

e99720344e wire-gen: ensure that tlv messages are correctly ordered
Our TLV serializer relies on TLV outputs to be ordered by type
number. Prior to this commit we relied on 1) the ordering in the
RFC to be correct and 2) users to be using a version of Python that
respects stable ordering of dicts (i.e. Python 3.7+)

Instead of relying on these implicitly, we now explicitly sort messages
by type number when the TLV sets.

Resolves #2956.
