f0ea4d60b9 onchaind: fix minor leaks.
Not actually leaks, but they do live longer than they need.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

85e3b43176 channeld, openingd: take into account option_anchor_outputs for fees.
HTLC fees increase (larger weight), and the fee paid by the opener
has to include the anchor outputs (i.e. 660 sats).

42a63e4416 tx: Strengthen transaction construction checks
We roll the `elements_add_fee_output` function and the cropping of
overallocated arrays into the `bitcoin_tx_finalize` function. This is supposed
to be the final cleanup and compaction step before a tx can be sent to bitcoin
or passed off to other daemons.

This is the cleanup promised in #3491

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.

b356dda0ba elements: Add explicit fee outputs to various transactions we create
Elements requires us to have an explicit fee output instead of bitcoin's
implied fee. We add the fee output mostly after sorting the other outputs
since that matches the behavior in elements itself.

dffe2f516a signature: wrap almost all signatures in struct bitcoin_signature.
This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.

We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_txid_to_hex() so it's reversed as people expect.
