Rusty Russell 0e805427dc tools/generate-wire.py: strip trailing whitespace on lines, fix bolt quotes.
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.

Rusty Russell 83298c030a wallet: switch over to withdraw in module, remove lots of unused code.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined.  Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

Rusty Russell c34c055d82 Makefile: use completely separate spec-derived files for EXPERIMENTAL_FEATURES
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.

niftynei 90b393ca1a hsmd/db: backfill pubkey information so that psbts signing works
the way we use PSBTs to sign things requires that we have the
scriptpubkey available on the utxo so we can populate the witness-utxo
field with it.

this causes problems if we don't already have the scriptpubkey cached in
the database, as in *some* cases we require a round trip to the HSM to
populate them

to get over this hump, we backfill any and all missing scriptpubkey
information for the utxo's that we hold in our wallet.

this will allow us to clean up the NULL handling of missing
scriptpubkeys.

lisa neigut 16656a85cf withdraw: refactor change output handling
We're not using the change_outnum for withdraw tx's (and the way
we were calculating it was broken as of the addition of 'multiple
outputs'). This removes the change output knowhow from withdraw_tx
entirely, and pushes the responsibility up to the caller to
include the change output in the output set if desired.

Consequently, we also remove the change output knowhow from hsmd.

darosior 273029f244 wallet: set nLockTime to the tip for withdrawal transactions
This sets the nLockTime to the tip (and accordingly each input's nSequence to
0xfffffffe) for withdrawal transactions.

Even if the anti fee-sniping argument might not be valid until some time yet,
this makes our regular wallet transactions far less distinguishable from
bitcoind's ones since it now defaults to using native Segwit transactions
(like us). Moreover other wallets are likely to implement this (if they
haven't already).

Changelog-Added: wallet: withdrawal transactions now sets nlocktime to the current tip.

Rusty Russell fe17acf07b TAGS: reformat to fix when PRINTF_FMT() used.
I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.

So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*.  So we remove it from definitions
and add gratuitous declarations in the few static places.1

darosior d393cda215 hsmd: encrypt hsm_secret if 'lightningd' pass an encryption key
This splits maybe_create_hsm_secret() in two parts (either encrypted
or in clear) for clarity, and adds an encryption detection in load_hsm().
There are actually three cases if an encryption key is passed:
- There is no hsm_secret => just create it and store the encrypted seed
- There is an encrypted hsm_secret => the provided key should be able to
decrypt the seed, if the wrong key is passed libsodium will nicely error
and hsmd will exit() to not throw a backtrace (using status_failed() as for
other errors) at the face of an user who mistyped its password.
- There is a non-encrypted hsm_secret => load the seed, delete the
hsm_secret, create the hsm_secret, store the encrypted seed.
