This includes anysegwit and the updated HTLC tiebreak test vector. It
also adds explicit wording for invalid per_commitment_secret (which
nicely matches our code already!).

Still needs some massaging (we print HTLCs as we add them, rather then
in the final order, which requires a manual move in one test vector),
but this makes it more trivial to compare the output with the BOLT 3
text after https://github.com/lightningnetwork/lightning-rfc/pull/852

The main change which affects us is that 2016 blocks to forget a channel
is a fixed number in the spec; we make this clear by renaming the
(developer-only) max_funding_unconfirmed to dev_max_funding_unconfirmed
and making it compile DEVELOPER only.

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

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
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.

This also means we subtract 660 satoshis more everywhere we subtract
the base fee (except for mutual close, where the base fee is still
used).

HTLC fees increase (larger weight), and the fee paid by the opener
has to include the anchor outputs (i.e. 660 sats).

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.
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
Changelog-None
Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.
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.

Instead of making it ourselves, lightningd does it. Now we only have
two cases of failed htlcs: completely malformed (BADONION), and with
an already-wrapped onion reply to send.
This makes channeld's job much simpler.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

This is the final step: we pass the complete fee_states to and from
channeld.
Changelog-Fixed: "Bad commitment signature" closing channels when we sent back-to-back update_fee messages across multiple reconnects.

This is an intermediary step: we still don't save it to the database,
but we do use the fee_states struct to track it internally.

This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

Rather than reaching into data structures, let them register their own
callbacks. This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.
Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

The way we build transactions, serialize them, and compute fees depends on the
chain we are working on, so let's add some context to the transactions.

* remove libbase58, use base58 from libwally
This removes libbase58 and uses libwally instead.
It allocates and then frees some memory, we may want to
add a function in wally that doesn't or override
wally_operations to use tal.

This fixes block parsing on testnet; specifically, non-standard tx versions.
We hit a type bug in libwally (wallt_get_secp_context()) which I had to
work around for the moment, and the updated libsecp adds an optional hash
function arg to the ECDH function.
Fixes: #2563

1. Rename channel_funding_locked to channel_funding_depth in
channeld/channel_wire.csv.
2. Add minimum_depth in struct channel in common/initial_channel.h and
change corresponding init function: new_initial_channel().
3. Add confirmation_needed in struct peer in channeld/channeld.c.
4. Rename channel_tell_funding_locked to channel_tell_depth.
5. Call channel_tell_depth even if depth < minimum, and still call
lockin_complete in channel_tell_depth, iff depth > minimum_depth.
6. channeld ignore the channel_funding_depth unless its >
minimum_depth(except to update billboard, and set
peer->confirmation_needed = minimum_depth - depth).
