This sets the nLockTime to the tip (and accordingly each input's nSequence to
0xfffffffe) for withdrawal transactions.
Even if the anti fee-sniping argument might not be valid until some time yet,
this makes our regular wallet transactions far less distinguishable from
bitcoind's ones since it now defaults to using native Segwit transactions
(like us). Moreover other wallets are likely to implement this (if they
haven't already).
Changelog-Added: wallet: withdrawal transactions now sets nlocktime to the current tip.
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 ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

We now have a pointer to chainparams, that fails valgrind if we do anything
chain-specific before setting it.
Suggested-by: Rusty Russell <@rustyrussell>
We used to match specifically on `is_elements && coinbase`, but we can just
hand off responsibility to libwally and then make sure we handle it correctly.
Turns out that if we have the init message contain both the chainparams as
well as a transaction that needs to be parsed we need to set the parser to
elements mode before we reach the transaction...
This is the main reason we started weaving the chainparams everywhere: being
able to compare the asset type with the fee paying asset tag, thus determining
the value of the asset correctly (we still treat any non-fee-paying assets as
having value 0).

In this one, we always send my_current_per_commitment_point, though it's
ignored. And we have our official feature numbers.

The largest change is inside hsmd: it hands a null per-commitment key
to the wallet to tell it to spend the to_remote output.
It can also now resolve unknown commitments, even if it doesn't have a
possible_remote_per_commitment_point from the peer.

`make update-mocks` is usually run in DEVELOPER mode, but then it includes
definitions for functions which aren't declared in non-DEVELOPER mode.
We hacked this in a few places, but it's fragile, and worst, now we
have EXPERIMENTAL_FEATURES as well, it's complex.
Instead, declare developer-only functions (but don't define them).
This is a bit more awkward if you accidentally use one in
non-DEVELOPER code (link error rather than compile error), but makes
autogenerating test mocks much easier.

This is the normal convention for this type; it makes using converters
a little easier. See next patch.

This is the other origin, besides `bitcoin_tx`, where we create `bitcoin_tx`
instances, so add the context as soon as possible. Sadly I can't weave the
chainparams into the deserialization code since that'd need to change all the
generated wire code as well.

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.

Instead of freeing proposals, which we did in *some* places, we just
set ->resolved and check that in billboard_update which didn't get it right.

This is important for things we automatically watched because it spends a
watch txo, but only onchaind knows the details about what the TX really is and
how it should be handled.

Weaning `onchaind` off its use of the internal bitcoin_tx input and output
fields, since we're going to remove them soon, I promise.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
The `wally_tx_input`s do not keep track of their input value, which means we
need to track them ourselves if we try to sign these transactions at a later
point in time.
