We introduced a minor issue in #5757 that was causing the manpages to
be added every time we regenerate instead of replacing them. The
script was a bit unscrutable, and we do this block-replacement in
several places I thought it might be a good idea to have a dedicated
tool to do it.
This allows us to have simpler Makefiles whenever we update a
generated block inside another file. It's python, but does not have
dependencies :-)
Changelog-None
We have a primary key that is spanning the `in_channel_id` and the
`in_htcl_id`. The latter gets set to NULL when the HTLC and channel
gets deleted, so we coalesce with a random large number that is
unlikely to collide for the primary key.
And make errors gcc-style, so emacs can jump through the automatically.

I know this is an unforgivably large diff, but the spec has changed so
much that most of this amounts to a rewrite.
Some points:
* We no longer have "offer_id" fields, we generate that locally, as all
offer fields are mirrored into invoice_request and then invoice.
* Because of that mirroring, field names all have explicit offer/invreq/invoice
prefixes.
* The `refund_for` fields have been removed from spec: will re-add locally later.
* quantity_min was removed, max == 0 now mean "must specify a quantity".
* I have put recurrence fields back in locally.
This brings us to 655df03d8729c0918bdacac99eb13fdb0ee93345 ("BOLT 12:

"sphinx_add_hop" takes a literal hop to include,
"sphinx_add_modern_hop" prepends the length. Now we always prepend a
length, make it clear that the literal version is a shortcut:

* sphinx_add_modern_hop -> sphinx_add_hop
In addition, we check that length is actually correct! This means
`createonion` can no longer create legacy or otherwise-invalid onions:

Many changes to gossmap (including the pending ones!) don't actually
concern readers, as long as they obey certain rules:
1. Ignore unknown messages.
2. Treat all 16 upper bits of length as flags, ignore unknown ones.
So now we split the version byte into MAJOR and MINOR, and you can
ignore MINOR changes.
We don't expose the internal version (for creating the map)
programmatically: you should really hardcode what major version you
understand!

sqlite3 added NULLS FIRST to their schema as of v3.30.1 but some older
boxes aren't updated (notably the author's own node box).
The default behavior for sqlite3 is to sort nulls first however, this
is *really* only needed for postgres.
As a simple fix (which will allow older boxes to not upgrade their
sqlite yet), simply strip out the NULLS FIRST keywords from sqlite3
queries.

We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an

To reduce the surface area of amount of a channel balance that can be

And initialize max to current height max when htlcs are already dead.

Postgres. That's clearer (MAX is used elsewhere for single columns),
