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).

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.
Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

There's a lot of it, and it means we can't `make check-source` on
these files.
Also bring bolt quotes up-to-date.

This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

We have to handle singletons which are arrays of variable-length entries:
this needs to be a ptr-to-ptr.
```C
struct blinded_payinfo {
u32 fee_base_msat;
u32 fee_proportional_millionths;
u16 cltv_expiry_delta;
u8 *features;
};
```
Before:
```C
struct tlv_invoice_tlvs {
...
struct blinded_payinfo *blindedpay;
```
After:
```C
struct tlv_invoice_tlvs {
...
struct blinded_payinfo **blindedpay;
```

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

Otherwise make thinks we're done, and we can get errors. Include

We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and
ALL_C_HEADERS. Then the toplevel Makefile knows which are
autogenerated (by wildcard), so it can have all the rules to clean
them or check the source as necessary.

Changelog-Fixed: Actually make the password argument optional for `guesstoremote` and `dumpcommitments` sub-commands, as shown in our documentation and help text.
Reported by `Barno` on #c-lightning IRC.
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`.
Changelog-Added: We now install `lightning-hsmtool` for your `hsm_secret` needs.
See: https://github.com/ElementsProject/lightning/issues/3717#issuecomment-644844594
It seems reasonable to add this to the standard install, and to document it properly as well, hopefully we can fill in the documentation better later on.
According to #3226, it looks like clang's LD error format has changed.
This patch adds the new format so we can parse the mocks successfully.
Apple clang version 11.0.3 (clang-1103.0.32.29)

`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.

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!
- we've moved tmpctx management to setup.c from daemon.c, so we update
the `check-tmpctx`
- `common_setup(char *)` is now a valid analog for `setup_locale`, so we
check for either in check-setup_locale
The formatting makes it harder for update-mocks, eg:
/* Generated stub for fmt_wireaddr_without_port */
char *fmt_wireaddr_without_port(const tal_t *ctx UNNEEDED, const struct wireaddr *a UNNEEDED)
{ fprintf(stderr, "fmt_wireaddr_without_port called!\n"); abort(); }
/* Could not find declaration for fromwire_onionmsg_path */
/* Generated stub for json_add_member */

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!

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.
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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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`.
