45bb1bfa3c hsmd: cleanup encrypted hsm_secret detection
This makes use of the constant defined in the previous commits to more
accurately detect plaintext, encrypted, and invalid seeds. We now error
on invalid seeds.

Changelog-changed: hsmd: we now error at startup on invalid hsm_secret
Changelog-changed: hsmtool: all commands now error on invalid hsm_secret

917f78a4f8 lightningd: group hsm_secret encryption key derivation
This avoids duplication of both logic and error-prone values, such as
the salt. Grouping all hsm encryption logic into a public API will also
allow us to fuzz it.

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.

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".

897c53ce1c tools/generate-wire.py: fix loop logic for towire_xxx_array

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.

bf4cac7fb8 tx: strip out witscript
now that witness script data is saved into the tx/psbt which is
serialized across the wire, there's no reason to use witscript to do
this. good bye witscript!
