This is stolen from the bitcoind source, so we use their style
(no tabs, 4-wide spaces). Clean it up and add the emacs magic to
maintain it in future.

As reported by Wladimir J. van der Laan. Valgrind will complain
about padding and unset fields, so memset the structs.

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).

Avoids much cut & paste. Some tests don't need any of it, but most
want at least some of this infrastructure.

If we're already attempting to connect to a peer, we would ignore
new connection requests. This is problematic if your node has bad
connection details for the node -- you can't update it while inflight.
This patch appends new connection suggestions to the list of connections
to try.
Fixes#4154
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.

This is simple, and we now can multifundchannel to every node on testnet
(one simply hangs once we connect).
Changelog-Fixed: Protocol: We now hang up if peer doesn't respond to init message after 60 seconds.
And add secp_recovery to headers, while we're at it.

dual funding needs the max-witness-len and utxo fields set for every
input. we should add them when we create a 'fundpsbt', so that every
psbt that c-lightning generates is dual-funding ready
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.

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.

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 simplifies our test matrix, as we never have to handle talking
to peers that specify one but not the other.
This is particularly important for option_anchor_outputs which
assumes option_static_remotekey.

We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.
We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
@thestick613 noticed that since tor version below 0.3.2.2-alpha
will not support V3 ed25519 address formats, the error handling
is not that helpful in the error message from cli.
So now we add an hint.

Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)
Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate
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

We did this originally because these types are referred to in the bolts, and we
had no way of injecting the correct include lines into those. Now we do, so
there's less excuse for this.

When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward. This changes it to directly
access those fields.
This is not only more elegant (60 fewer lines), it would also be
more cache friendly. That's right: cache hot singles!

Note that it's channeld which calculates the shared secret, too. This
minimizes the work that lightningd has to do, at cost of passing this
through.
We also don't yet save the blinding field(s) to the database.
