Add memleak_ignore_children() so callers can do exclusions themselves.
Having two exclusions was always such a hack!

If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.
This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.
Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.
W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).
Anchor outputs are ignored by the clightning wallet, but we keep track
of them in the bookkeeper. This causes problems when we do the balance
checks on restart w/ the balance_snapshot -- it results in us printing
out a journal_entry to 'get rid of' the anchors that the clightning node
doesnt know about.
Instead, we mark some outputs as 'ignored' and exclude these from our
account balance sums when we're comparing to the clightning snapshot.
1. tal_strndup(.., str, strlen(str)) == tal_strdup()
2. tal_strdup also takes(), so document that.
3. Avoid passing 'struct sha256' on the stack: use ptr.
4. Generally, structures shouldn't keep pointers to things they don't own.
In this case, mvt->node_id.
5. Make payment_hash a pointer, since NULL is more natural than an all-zero
hash.
And add NON_NULL_ARGS() to the functions; it's cumbersome, but make it
fairly clear what params are optional.

we used this originally to suppress duplicate issuance of coin-move
events; we're assuming that any plugin expects duplicate events though
(and knows how to de-dupe them), so we no longer need this logic.
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.
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.

This makes init a two-stage, and causes some code hoisting.
And we can now send all the HTLCs in a single message, since we have
an 128MB limit and each HTLC is 37 bytes.
This breaks the onchaind stresstest, which uses canned internal messages.
It's time to finally delete that.

In particular, this made valgrind OOM, and chewed much CPU. I dumped the
input and output into a file to allow easy replay.
This will break as soon as we change onchaind's wire format, but it will
serve its purpose until then!

1. Rename memleak_enter_allocations to memleak_find_allocations.
2. Unify scanning for pointers into memleak_remove_region / memleak_remove_pointer.
3. Document the functions.

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.

Note that other directories were explicitly depending on the generated
file, instead of relying on their (already existing) dependency on
$(LIGHTNINGD_HSM_CLIENT_OBJS), so we remove that.

This is best done by passing `struct bitcoin_signature` around instead
of raw signatures. We still save raw sigs to the db, and of course the
wire protocol uses them.

Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.
We save the amount + witness script + witness program (if known) to
the PSBT object for a transaction when creating an input.
For the moment it's a complete tx, but in future designs we might only
be given the specific input which closes the channel.

It returns NULL, so you can simply `return fromwire_fail(...)`
if you want to return NULL in this case. Use that more.

Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core
