There are 3 commands for opening a channel with dualfunding.
`openchannel_init` is the first of these.
It initializes the open-channel dialog, and stops once we've run out of
updates (input/outputs) to send to the peer.
`test_opening_tiny_channel` fails if EXPERIMENTAL_FEATURES is on because
we don't include the anchor in our reserve if we're the channel opener.
Seems fine to include in all cases?
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.

clang did the hard work here:
openingd/dualopend.c:958:42: error: result of comparison of constant 'WIRE_DUAL_OPEN_FAIL' (7003) with expression of type 'u8' (aka 'unsigned char') is always false
[-Werror,-Wtautological-constant-out-of-range-compare]
if ((msg_type = fromwire_peektype(msg)) == WIRE_DUAL_OPEN_FAIL) {

We can use a fixed value and close the channel if they don't cover their
amount; this wasn't really helping with anything other than setting a
floor for an expected feerate
Greatly simplify the changeset API. Instead of 'diff' we simply generate
the changes.
Also pulls up the 'next message' method, as at some point the
interactive tx protocol will be used for other things as well
(splices/closes etc)

v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.
includes a migration for existing channels
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.

It's now only needed by devtools/mkfunding, so include a reduced one
there, and this also means we remove tx_spending_utxos().

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.

We're going to make experimental versions of these completely separate files.
Also remove the dependency on the Makefile itself: it simply causes
unnecessary churn. We can always force-rebuild when we change a rule.

And document exactly what it does: insist that an HTLC can pass of
this value (module assumptions of feerate).
Note that we remove the "is_opener" test from the capacity calculation
for anchor fees: it doesn't matter which side it is, someone has to pay
for anchor fees to it deducts from capacity.
This change breaks the test, which we rewrite.
Changelog-Changed: config: `min-capacity-sat` is now stricter about checking usable capacity of channels.

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.

It's not all that rare to do these operations, and requiring annotations
for it is a little painful.

Fixes: #3815
Changelog-Fixed: Fixed a deviation from BOLT#2: if both nodes advertised `option_upfront_shutdown_script` feature: MUST include ... a zero-length `shutdown_scriptpubkey`.
The main change here is that the previously-optional open/accept
fields and reestablish fields are now compulsory (everyone was
including them anyway). In fact, the open/accept is a TLV
because it was actually the same format.
For more details, see lightning-rfc/f068dd0d8dfa5ae75feedd99f269e23be4777381
Changelog-Removed: protocol: support for optioned form of reestablish messages now compulsory.
