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.

This is best-practice (to ensure prototypes match up), but there were a
few places we didn't (at least, directly). Make it a requirement,
either of form "foo.h" or <dir/foo.h>.
The noise is the change to our print templates.

We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

We want to use this to handle the simple description for channel_type.
It also needs to handle variable-size types (just like subtypes).

This touches a lot of text, mainly to change "if `option_anchor_outputs`"

option_will_fund changes the to_remote/to_local commitment tx
outputs by altering the CSV lock for leased channels.
We need to grind/scan for these outputs now, provided the defaults don't
work.
We don't handle our own cheat txs: rather than crash, we should just
log broken and limp along.
This also makes our upcoming penalty test easier: we don't have to
spin up a new node.

The commitment tx uses the same feerate as the HTLC txs (which we have
to grind to find), but we can't use it directly since the fee could be
increased by the presence of dust HTLCs. We can still use it to cap
the maximum though.

Changelog-Fixed: onchaind is much faster when unilaterally closing old channels.
We try signatures to see which HTLC (we can have many) is the right one;
we can trivially match htlcs against commitment tx outputs, but the CTLV
can vary, and that's inside the htlc tx itself.
By sorting them, it's easy to skip comparing duplicates:

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!

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).

There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.
This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.
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.
